Be more careful with your stuff
 

At both regionals that I went to(Seattle and Spokane), people were just randomly leaving stuff like backpacks, laptops, food behind and the person would leave the seat to go the pits or something and find that their stuff is either gone or can't find it because their seat is taken.

I know for a fact that at Spokane, 4 sets of car keys were lost and 1 wallet. In fact people were actually trying to get/steal the wallet by guessing the amount inside.

SO please, be more careful.
