90mph in a 65mph zone (I-5, Oregon) in 1989. The car was a Mustang, but it was my friend's car and I don't remember the year/engine size. I got a $225 ticket. The judge reduced it to $125, and my friend's mom paid $80 for me.
100mph in a 1969 AMX. That was really fun, but really stupid. I was in a 40mph zone (I think). My uncle's car. He knew I loved the car so he let me drive it. I think he knew that I would speed, so we just didn't talk about it.
110mph as a passenger on a Honda (doh! name escapes me, Magna?) motorcycle. We covered a 12 mile stretch between Veneta and Eugene, Oregon, in like 8 minutes or something. It was amazing. We could pass a car that was doing highway speeds like it was standing still. It could have went faster, but we weren't stupid. Oh wait. Yes we were.
All those examples are over 10 years old. Because I'm 30.
