Some of those look like they would be fun to ride. How many critters come out at night? See you were doing some tracking. LOL
They're the best ones; roads abandoned by the county long ago but still "maintained" by the farmers that still use them to access their fields and kids that go "mudding" in their pickups. Nighttime travellers that I've seen include raccoons, possums, foxes, bobcats and coyotes. I've never seen a deer riding dirt or gravel roads at night.
