Growing up in Sudbury, MA I had a 3-mile route for fast runs from my parent's house by the Wayside Inn, a local "colonial" landmark.
I'd run 5 minute pace on a good day. One such day I was rolling towards an intersection - a car was coming up to the intersection simultaneously and I met eyes with the driver. He gave me an F.U. look and continued at speed.
We hit the intersection together and I bounded up over the hood of his car touching it once with my foot and continued on my way.
I did not look back, and the M.F. did not come after me. It felt quite good to my 18-year old self...
