Chris;<br><br>I hope I'm not being presumptous in throwing my 2 cents in here, but when I took my Wilderness First Aid Instructor's ticket in February, the Instructor-Trainer started off by dividing the class into groups and telling each group they had 10 minutes to go through their packs and put together an improvised First Aid kit. Since everyone in the class was a First Aid instructor, there were more commercial First Aid supplies than there were improvised ones; but the two things that nobody thought to provide were a cervical collar and a bedpan. Apparently, hardly any student in Wilderness First Aid thinks of providing those, unless they've taken the course before. <br><br>An excellent book on the subject, IMHO, is the St John Ambulance Official Wilderness First Aid Guide by Wayne Merry. (ISBN 0-7710-8250-9, if you're interested.) That's the official textbook for the Wilderness First Aid courses I'm now qualified to teach, fwiw. If you can get hold of a copy, I'd be very interested to hear your opinion of it, btw.<br><br>Thanks for all the great advice, too.
