Barefoot running and what it does to me ... and maybe you too

I started to notice that when I am running barefoot, I am much more aware of my surroundings.
I don't mean the path in front of me, but the peripheral recognition of things is just going crazy on me.

So, I am up at 4am, getting ready to run the trails.  I am at the trailhead around 5am and start running.
I notice a couple of deers, about 30 feet off the trail, standing in the woods and they are eyeballing me, I looked into their direction since I had the feeling that I was being watched.  Whoa.  Really?! Two deer?
