I have this recurring nightmare. I'm on a dayhike and somebody asks me ( expert) to demonstrate some deadfall or I.D. a LGB (little grey bird.) My strategy is to plead the need for a toilet break, run behind a big bush and shake it vigorously while quickly thumbing through my SAS GEM or Peterson field guide. We are all products of other's efforts. Gene Ward comes from the USAF, and remember an elephant is a mouse built to MILSPEC, ergo the complicated shelter. I recently co invented the Origami folded rock tarp deployment. NO, you won't see this as an addendum to the excellent tarp resource onsite. We were cold, stayed out later than we should have and the crowded canyon trailway anything but conductive to a geometric, textbook perfect tarp. Even I know enough not to tie paracord to Poison Sumac <img src="/images/graemlins/blush.gif" alt="" /> We sort of wrapped it around us it like a Taco Bell Burrito made by a first day employee. I think 2 day courses are rediculous beyond very, very basic instruction. Instructors are under a great deal of peer pressure, competition and simple hubris to make everybody a 'snake eater' for $99.99 If you learn something new consider it time well spent. There are lots of instructors in AZ. My favourite Is Reevis Mountain School. It is a magical place and you have fun too.
