We brought lawn chairs, sat around talking all night. We also had a tent to change in, but never slept. Actually, one of the guys did sleep for about 2 hours. You should be getting a schedule of the themes for each hour. Some of our events last year were a Disney hour, had to wear something Disney. Wedding hour, some folks came dressed as brides/grooms, animal theme, pajama hour--that was fun! I took some of my mom's curlers stuck them in my hair with a head scarf, tossed on my raggedy bathrobe, (shorts and T-shirt under) slippers and walked around yawning and scratching my behind...they give out raffle tickets for those walking to the theme of the hour and extra for some. There was a military hour, oh just so much. There are team pics, team shirts, you name it they have thought of it. Some groups sell food, beverage. We sold cabbage and noodles, jambalaya (sp?). FD and PD sold chili others sold novelty items...it is like an all night bazaar.
The moving part is the beginning where survivors walk out, there is a candle processional, and luminaries that are lit along the track in honor/memory of friends and relatives that are purchased before the event.
Your team captain should be getting info to you about all this stuff.
