Outdoor Scavenger Hunt

I remember doing something like this in Girl Scouts when I was a kid. It's simple drawings on a paper. Kids can do a scavenger hunt while they are in the park, out on a hike, hanging out at a boring family reunion....I want to laminate mine so we can use it over and over. 
This could easily translate to a city scavenger hunt too. You could draw a hydrant, a blue post box, a parking meter, a bird's nest. The list goes on and on. 
Happy Hunting!
