One of the coolest things that has happened to me running happened yesterday while I was out on the trail at Gilbert State Forest in Foxboro, MA. I turned this corner and heard this "whmp, whmp, whmp" sound and looked up to see this huge owl in front of me taking off and going up into a tree.
Now I generally hate to stop but I just had to stop and check this big guy out. It was SOOOOO cool.
Sights like that will definately keep your head up while training, and you dont see too much stuff like that running on the roads.
