Scavenger hunt creation

I am taking some students in a field trip next week. They will have approximately 30-45 minutes 'free' to eat lunch and walk around. I wandered taking photos for a scavenger hunt activity I plan to give them titled "art is everywhere". My hope is that it will encourage them to see the beautiful details in the city as well as learn the locations of a few major art galleries in the city. Again, no art making of my own today but that's alright.
