Found this in northern MA, about 5 miles inland from the coast in the driveway of my commercial office park. Surroundings are mostly homes and woods.

My wife thinks it's a snapping turtle. It's a baby, the shell is maybe a little over 1", it's caked in mud, I didn't want to wash it off because I was afraid his shell might still be soft.

I thought my 2.5 year old son might really enjoy watching him grow, but not if it's a snapping turtle!
