for my friend's sweet 16 party, we are doing around-town group scavenger hunts. what are some good list items?

the hunt will last around 2-3 hours, and we will be split into groups of four and each group will take a car. the list will have about 300 items, so that teams can pick and choose which ones to do. there can be items that involve taking a PHOTO of the team doing something, or list items that require the team to bring back actual ITEMS. any ideas? al are appreciated! thank you
