Ha! Fun. I did much the same a few years back on a little Honda Ruckus. The small wheels make them really twitchy in mud. I managed to stay upright, but I was sideways, with both feet in mud up to the ankles.
I was out again today, as well, with the same results; no sightings or sign at all. My excitement came on the way back out. I had gone through an open gate for a work area (repairs of last fall's huge washouts) that had a sign saying the gate would be locked at 4:30 PM. I got back there at 2:10 to find it locked, and no one around. Though I had heard some chatter on the radio earlier, no one had said "We're leaving, get out". Way out past cell service, of course. After some discussion, my son, our lady passenger, and I decided to build a bypass around the gate by towing some large boulders out of the way and digging into the uphill bank to make a shallow enough slope to keep the truck from flipping over. Two hours later, with only one minor dent in the rear driver's side door, we were on the other side of the gate, and headed home.
