comment How to find new poles for old tent?
@Whats: What "blueprint" information do you want beyond the measurements I already gave?

comment How to find new poles for old tent?
That might fix the one immediate problem. But, all the pole pieces are 30 years old and have all been subjected to about the same stress. I'd really like to replace the lot.

comment How to find new poles for old tent?
It doesn't appear to be that easy. Yes, it's easy to find "replacement tent pole", but most seem to come down to two products, one from Coleman and one from Texsport. Those two and other "replacement poles" are all too thick and too long. They claim to come with "pole caps", but nobdy seems to mention the diameter grommet they are intended for. I am afraid that too thick would cause too much strain for the small radius of curvature of my tent. Too long could possibly be cut, but that is tricky and can easily damage it. It's not as simple as you make it out to be.

comment What are the major difference between a regular sleeping bag and one designed for women?
Actually #2 is saying that women need less insulation to feel comfortable in the cold. That is actually contrary to my personal very sample-limited observations.

If you're in a group, use the penguin method.

comment What are the odds that I stand a chance against Wild Boars?
It might work with a adult or two, but acting aggressive to a sow with babies is a really really bad idea.

comment Should I be worried about bears when sleeping in a hammock?
I guess it depends on how bothered you are about seeing bears and other critters coming, as apposed to being unaware of them when you're in a tent. Mosquito issues sound like a much bigger deal.

comment Identifying named peaks from the summit of a north-american peak
I don't know of any peak-finder, especially one you can take into the backcountry with you. However, I don't see why using a topo map needs to be "painstaking". I have used them often for this purpose and never considered it particularly difficult or burdensome.

comment How to deal with little flies flying into the eyes?
Yes, I mean clear transparent goggles. I have some I use for winter hiking in some conditions and they are clear. I think they were marketed as ski goggles.

comment How to deal with little flies flying into the eyes?
I haven't tried this personally, but how about goggles you would use in winter during snowstorms or for skiing? The vent holes on those are usually covered with a thin breathable foam so that snow powder doesn't get in. That should keep these flies out just as well.

comment What is the safest way to purify water?
I looked around a bit but couldn't find a definative source. Back in the early 1980s everyone pretty much used backcountry water in the WMNF without thinking much about it. By the late '80s that was not done anymore. Giardia had been found in several fairly deep backcountry sources, so one had to assume it could be in any water, even if it actually wasn't in most. The one I remember specifically was a spring on Signal Ridge, on the south shoulder of Mt Carrigain, but there were others. Since giardia can pop up quickly, it's smart to assume any water could be infested.

comment What is the safest way to purify water?
Perhaps what you say is true for the Sierras, but is certainly NOT true of other areas. Various places in the White Mountain National Forest of NH were tested, and enough giardia found that there is a overall recommendation not to drink the water directly. If giardia is the only issue, then even filters work since these buggers are rather large. I am surprised you were the only one to mention germicidal UV. It seems like a really good idea to me. 90 seconds for a liter and you're ready to drink. By the way, I wrote the firmware for the latest SteriPen, the Ultra.

comment What's the problem with electrolyte imbalance and how do I mitigate it?
Intersting comment about Gatorade not containing enough electrolytes relative to the water. I was told exactly the opposite in a SOLO course. The instructor said the Gatorade acknowledges this in scientific circles, but for reason of taste and marketing make their drinks stronger than necessary. The instructor went on to recommend 1/2 strength by adding water. I use about 1/2 to 2/3 strength routinely, including hiking most of the day in the desert in summer, and it seems to work fine for me.

Whoever downvoted this, it would be useful to explain what you think is wrong, incorrect, confusing, misleading, etc.

comment Dealing with wildlife in the desert of California/Nevada in general and in the White Mountains in particular
@Masked: Cold weather is different. I hike around New England in the winter, and the issues are different. In the winter you can get dehydrated and not realize it. When it's hot you get thirsty. You do lose a lot of water when its cold, but much of that is in your breath so is pretty pure. You should always at least think about electrolytes, but that is much less of a problem in the cold.

comment Dealing with wildlife in the desert of California/Nevada in general and in the White Mountains in particular
@gerrit: My electrolyte incident was in the middle of the summer on the west side of the Tonto basin. That place gets pretty hot, and that was a hot day as I remember it. 115F is my best guess. The hottest I've encountered so far in AZ has been 121F according to the rental car. That was in the Kofa refuge. I was hiking then with my usual (by that time) diluted gatorade and felt fine.

comment How can you navigate without a compass or GPS
This is just plain wrong. Different species of moss and lichens grow on different sides of trees dependent on a lot of factors. At the northern end of a species' range it may well appear mostly on the south side of trees while other species in the same forest are on the other side or all around depending on local microclimates. Just forget about the moss myth, it will waste your time and keep you from observing the things you really need to pay attention to.
