2 guys passed me going down a dirt road in a smaller car holding a canoe on their roof. The driver and passenger each having an arm out the window holding the canoe down. They passed me doing about 45mph and a few seconds later the front of the canoe caught some air, flies up about 25 feet and does a flip, right in front of me. Luckily I had some room to avoid the obstacle now lying in the road.
Riding thru Kansas during a wind/sandstorm last fall I tried driving perpendicular to the wind for a few miles. Not a good idea as I had to dodge and then was struck by several tumbleweeds. Yes, they do hurt and I won't do that again.
Nothing like riding with your full face visor up and have a bee fly in with the visor shutting closed as I tried to shake the bee out. I was lucky not to get stung.
I did not see this but my buddy lived near a pig farm. The road that went by the farm was perfect concrete with a set of banked S turns that we used to take as fast as we could. Coming thru the esses one morning on his 69 Bonneville a full grown pig was right in his lane. He had no time but managed to hit the pig square dead on. He didn't go down and the pig walked away.
