I have a friend who sells geraniums as a fund raiser every spring and she wanted some pictures of the flowers' colors to help her sell them next year, so I went up to her house with my trusty Canon to oblige.
We got a bit of a surprise on her driveway, Crotalus viridis viridis, alias the Prairie Rattlesnake. It was just a little bugger, but practically invisible against the concrete.
This is why, when we garden in the spring and fall, we carry a tomato stake with us and let it probe a path ahead of our feet.
