Came across a deer mouse on the trail Saturday, the trail dirt was only about 7-inches wide the the mouse was walking in a perpetual 9-inch circle. I stopped, leaned over the bars to watch it, it cocked its head sideways and stared back at me with one eye as it continued circling. I was a little shocked so didn't think to video it
, but as I rode a way I timed its circle so my 4.8" tires didn't crush it. Got home and google tells me it could have a brain parasite, brain tumor, inner ear infection, or had a stroke. Probably should have squashed it...
