First time riding in the rain, slid around a corner. I wound up wedged under a parked car with the bike between my legs. Got a little scraped up and a pretty bad burn on my leg from the muffler.
I had rented a car to go work a day on a movie set (my big break - ha!) and while I had it I drove an extra 75 miles to visit my parents. Late that night, driving back to the city, I was excited about finally driving a reliable car so I pushed it. Got ticketed for 85 in a 55.
