Oh, I've done made those. They're pretty fun. Without knowing your area it's hard to make clues specific to your town. Here's some I've used that will probably be good anywhere in the US.
Food by Peter Pan's friend. (Wendy's)
Primate Adhesive (gorilla glue)
Amazing staff of life. (Wonder Bread)
A Danish toy store. (The Lego Store)
Your team playing duck duck goose in a public place. (fun way to embarrass some people)
Basically come up with riddle like clues for common things. Also, if you have any major landmarks or maybe stores that used to be other stores that could work too.
