I know exactly what you mean! I was riding north, right by the chess pavilion, and there was some guy walking down the middle of the path. I called "on your left" a few times, but he didn't budge. Finally I screamed "Move it!!!" and he STILL didn't move. I couldn't swerve into the opposite lane because someone else was walking in it. So i just ran into him.

I missed all the beautiful weather last week because I was at worked > 80 hours last week. So sad.
