When I run, I do look around me a lot. I tend to notice small animals, prints and other spoor, off-shooting trails, birds, interesting trees and cloud formations that seem to be unnoticed by some others. During my run last night, I noticed all this, and also looked behind me a fair amount. Along the way, I saw 4 bucks and a doe on the hillside, one of which had been radio-collared and ear-tagged. That was the first time I'd seen a tagged and/or collared mulie. So maybe my heightened awareness made the run a little more interesting. It did make it a little slower. It's hard to maintain pace while gimballing my head around 360°.
