Logistics concerns the basic behind-the-scenes work, organizing, communicating with vendors and guests, troubleshooting, etc. As for the dress code...dress for the weather! Volunteers with be getting 3/4 sleeve t-shirts as they arrive, but the morning hours are definitely going to be cold. The festival goes on rain or shine, so volunteers should also keep possible precipitation in mind as well. As there will be nowhere for volunteers to stow any bags or personal items, make sure they pack light. (Cargo pants with lots of pockets are probably a good choice.)
