comment Wood versus plastic trail signs?
@Olin Yet another one in the MHNF, also with dark lettering. If the bolts are any indicator it might be somewhat older.

@Olin That sign is ostensibly on a trail in the Mt. Hood National Forest, but one I've never visited. Here is another sign that appears to be of the same type. Perhaps I can ask one of the rangers in that area how old those signs are, next time I'm out that way.

comment How should I remove a tick?
On Amazon.com there is a harsh review of this product: "We have tried a number of times to remove adult deer ticks from people (ourselves) with no success. The TickKey just slides right over the tick. It will remove a tick that has fed on a dog. This was advertised as being able to remove deer ticks, in our experence(sic), IT DOES NOT WORK." There are other reviews which state that it does not work on small ticks. If you have to wait for the tick to swell up with blood before it works that's not good. What is your experience? What is the specific species of tick in your area?

@Olin What do you make of the construction of this sign? It looks like bleached wood but the lettering is dark and clear. I suppose it could have been made of bleached wood to begin with, but if it weathered into that state and remains that legible it impresses me. Does the lettering look burned on to you?

comment Wood versus plastic trail signs?
@OlinLathrop You're welcome. I was afraid that there might be a durability problem with paint; perhaps that style could be emulated in composite however. None of these are my own pictures, and frankly I don't spend a lot of time looking at signs, but if the Bell Creek sign is composite it's a departure from the standard around here. However since it appears to be new in the picture that is possible.

comment Wood versus plastic trail signs?
@gerrit I do see the advantage in that, but at the same time I don't like it. I prefer an area to have its own local flavor: ideally style with flair yet which blends with the surroundings, a la Frank Lloyd Wright; not ugly uniformity, a la McDonalds.

@gerrit I would hate to see signs like that on the trails around here. Sorry, but yes they are ugly.

comment Wood versus plastic trail signs?
I don't believe there is a signage tag; rather I'm suggesting that it will be more general and therefore useful (in combination with other tags) than trail-signs. Since you don't object I shall retag, but ultimately it's up to the moderators to decide. Also, don't worry about the picture; I'll add some myself (in an answer) with my own thoughts on the matter.

I'd like to retag this with trails and signage following this logic. Do you object?

Interesting question. Do you happen to have a picture of one of the plastic signs?

Thanks for the reference. You've got my +1.

comment “Used” top rope when bouldering
Seeing rope worn out from repeated short falls, without apparent extreme abrasion, leads me to think that due to the concentration of load in a bent rope (the purpose of my including the second quote) does in fact push some fibers past an elastic limit and slowly degrade the rope. I'm certainly not claiming to be an expert on this and I'd love to know if you have other information or theories.

comment “Used” top rope when bouldering
@BenCrowell Okay, that's a valid criticism and I appreciate you taking the time to make it. Could you provide a link to Aging Rope? I know that nylon does very well in flex cycle testing, losing very little strength over thousands of cycles (unlike aramids), and I also know that load cycling (presumably below the elastic limit) without a bend also has little apparent affect on strength. Nevertheless the ropes do wear out. Do you assert that it is entirely a matter of abrasion? Direct infiltration? (continued)

Cow tipping doesn't actually exist. It's a joke.

@BenCrowell Please see my addendum. I mean you no disrespect, but as stated there I believe the subject matter warrants fastidious scrutiny.

comment When should I retire my rope
@BenCrowell I agree with (my understanding of) what you wrote. All I meant to communicate is that a short factor-1 fall puts (almost*) as much stress on the rope as a long factor-1 fall, just over a shorter area, which I think is what you just said, but more clearly. (* Almost, because there are common energy absorbing elements in the system besides the rope that do not change with the length of fall, therefore a very short factor-2 fall will not reach as high a peak force as a full-rope-length factor-2 fall, even momentarily, and the impulse is much longer as well.)

comment Resoling climbing shoes yourself
No experience, but this seems like the sort of thing on which you'd spend more in the processing of learning to do it right than you would having it done professionally, even repeatedly.

comment “Used” top rope when bouldering
@OutlawLemur Yes, so long as the rope is still serviceable according to the Beal guidelines. In a top-rope (slingshot) setup a fat, fuzzy rope will make it a little harder on the belayer, but not much else. For lead the same rope will cause much greater rope drag making it really hard on the leader unless the pitch is short, straight, and vertical. Of course if you mean by "only for comfort" that you don't intend to weight the rope, and is serves only as a true safety line, then I wouldn't anticipate much wear on the rope anyway.

Ben, as a friendly heads-up I just posted an opposing answer. Please read it and rebut as appropriate.

comment When should I retire my rope
@BenCrowell Indeed, and I didn't mean to imply otherwise. I meant that comment a a parenthetical, and merely that gym falls can still put significant stress on a rope. I think there is a tendency to look at a short wall and figure it's small stuff and won't really stress your equipment, when in fact the forces can be quite high and they get concentrated on a short section of rope near the ends. Do you agree with that? Perhaps this answer wasn't the best place for this.
