I only attended on Saturday, but was still able to attend 5 presentations and spend some time checking out the exhibits. I bought a new NRS map case and some dehydrated fruit for my spring trip. So aside from parking, admission and expensive food, I got out of there only spending about $30.
I saw 3 photography presentations... all 3 were different from each other and very interesting. Then I saw the food dehydrating program... not sure I will ever take the time to dehydrate my own food, but it was still interesting. JStroke's program was again great! I posted a few shots over on here: http://bwca.com/index.cfm?fuseaction=forum.thread&threadId=1000641&forumID=12&confID=1
I did remember to wear my NibiMocs nametag but didn't see any others.
