Photo scavenger hunt

It's my husbands birthday next weekend. He's picked up street photography as a hobby the last couple years and I wanted to incorporate it into my plans for his bday. Would you mind sharing some ideas for a photography scavenger hunt?

He's injured his leg recently and currently limited on foot so I was planning on driving around the city and taking him on a water taxi on the river after brunch.

I plan on getting him to share his photos on a slideshow with some cake and coffee at home for the two of us 🥰

Thank you in advance for sharing
