Agree totally on here about the courtesy plow. What a PITA when someone does that. When I see that about to happen I swing my arm in a big circle and try to get them to continue through at speed. Never really works.
Of course we (Zsqure and Me) had the opposite happen on Sunday. We were about 60 yards apart and heading towards each other on a corner of our channel (river) area and a I/O Cuddy comes speeding through between us at about 35 mph. He was probably about 35 feet away when he passed by me, doing the I/O stand and drive... I kind of blew it off until about 5 minutes later he went back through the other way and was cutting in front of people. Then I knew he was a pecker head!!
