And one other thing of which you should be aware, if you climb in the southwest, is snakes - particularly rattlesnakes.

There are a couple of places where we go climbing (class 3) and also rapelling where rattlers tend to hang out and sun. Our rule is "don't put your hand/feet where you can't see".

Yes, I know this is not always possible but you have to use common sense.

Just a thought.
