Today I saw those purple boxes in the trees like Lynnis was talking about. Luckily for me one was in my friend's lawn on her tree. We didn't know what it was, but there was a sign stapled on the tree saying it was put there by the Department of Agriculture. We looked on the website they put on there, and it was really interesting. So far I've only found two purple traps, but now we can make in to an activity when we're driving instead of counting red trucks.
