Oh! This brings back (bad) memories from college!!! I didn't love being cold and wet and dirty like the boys did, and crawling on my belly through those tight squeezes wasn't very appealing either. LOL But I'll bet this group had fun. And they look totally prepared. Those helmets are a BRILLIANT idea. Love your use of themed elements.
I'm totally going to be stalking your gallery, too -- I'm going to try to switch to 8.5x11 pages this year, and I can see that you have lots of them and you do them well.
