I've been attacked twice by Canada geese, both times in Ohio. Springtime is rutting season for the birds and the ganders get very, very aggressive. The first time I was on my motorcycle headed into work, and the damn thing did his best to try and knock me off my bike. I finally managed to exceed his speed limit through a parking lot.
The second time, the damned goose just decided to attack the side of my vehicle. Apparently he didn't like the styling or color. Just a big THUMP when he ran up against it. No damage to him or the vehicle.
