I'm attending the second session of the NASS, and I was reading the checklist of what you need to bring. 4 pairs of athletic shorts, 10-12 pairs of socks, 10-12 pairs of undergarments, 2-3 towels, twin linens, pillow/pillowcase, 2 pairs running shoes, one piece swimsuit, small fan, travel alarm clock, photo id as far as civilian clothing goes, I think I'm going to stick to khakis and such. the letter advised NOT to bring excessive valuables. I was wondering about things like cameras, cell phones, and things like that - luxuries. I know they're not neccessary, but I didn't want to bring things that would be frowned upon.
