comment Hiking popularity in North America vs. Europe
Yeah, I've been downstream of the restricted area but still in the park after a thunderstorm upstream. Somehow the water got concentrated into something that resembled a tidal bore. Not only did the water level rise quickly, but the first bit came as a single wave, then went up over the next minute or so more after that. Very impressive.

comment Is cougar hunting legal?
Yes, cougars are allowed to hunt. If not, how do you expect them to catch food and survive?

comment How much heat can a candle lantern provide while winter camping?
@Russell: Oops. I was thinking 8x3 and somehow managed to write 8x4, then propagated that error further down. That is all fixed now. 8x3 feet is very small when considering the dissipation surface of a tent. Keep in mind we're talking about a tent, not a bivvy sack or the like, meant for winter use. Also, the dissipation area will be more than the footprint area. Again, I was being conservative with the numbers to point out that it clearly won't work. If you disagree, show where the math or the logic is wrong. Claiming "doubt" is no useful information at all.

comment Can I mix fuels when using the MSR whisperlite international stove?
@Nisan and whatsisname: Any stove capable of burning white gas is capable of burning regular gasoline as these are chemically mostly the same thing. The issue is the additives which can cause problems, some over the long term. As Nisan says, it's "not recommended", and as whatsisname says, burning white gas is "better". We are all saying the same thing here, so I don't understand the objections.

@Nisan: It seems like you are just repeating what I said. What point are you trying to make?

comment How much heat can a candle lantern provide while winter camping?
@sgd: Saying snow has any particular R value makes no sense. Perhaps some particular type of snow at a particular depth may have a reasonably repeatable R value, but just "snow" doesn't. In any case, for this snow to matter in the analisys above, it would have to cover the tent. A tent covered in snow would be better insulated than one that is not, but only for temperatures below freezing. Snow is essentially a infinite heat sink at its melting point.

comment Kepler Track: Brod Bay to Iris Burn Hut in one day?
What is the total distance you are planning on hiking in one day? The lettering is hard to see on the chart. Also, it you're not in such great physical shape, fix that before you go. Just running a few miles at lunch time or whatever can make a lot of difference.

comment Adequate Shoes for Travel
Hey, us American's aren't that dumb. We also know all Canadians wear plaid flannel shirts, carry large axes, end sentences with "aye", and are named "Nanook".

comment Is it dangerous to sleep in a tent alone in a forest in -20?
The tent size issue for heating makes no sense. The 30 W or so your body puts out raises the temperature in even a small tent a insignificant amount. See the recent discussion of a candle raising the temperature, and that was assumed to put out 100 W.

comment What dried vegetarian foods have the highest ratio of calories to volume?
Peanut butter may be a very dense food in terms of sustinance per pound, but it is also serious bear bait. Anything you manipulate it with will have a smell. It's not quite as bad as frying bacon and eating it in your tent in the evening, but I wouldn't take peanut butter to bear conntry.
