Bring extra shirts for team members/family members who don't have any. (No selling though...)
Don't assume you'll have lunch (maybe just for Silicon Valley people). At SVR, all the food places were closed on Friday and Saturday since SJSU had no school or whatever. Sigh.
Don't lift things that are too heavy for you, and don't be afraid to ask people to help you! Sigh x2.
And most importantly, talk with other teams! This is possibly the only place (until college) where you'll be normal!! (Who knew
)
