What's some riddles for stoplights and street turns for a scavenger hunt?

I painted a picture frame with me and my boyfriends picture in it and i wanted to hide it somewhere in our city, whats some clever ways of tricking him when i give him the list of directions to follow? he's really smart and he found my last hidden gift so easily it wasn't as much fun lol whats some ideas to stomp him? xD thanks!
