Ton-up: exceeding 100 mph on a motorcycle. There was a time when this was difficult and dangerous.
Mods: Fashion-conscious scooter riders commonly found in England in the late 50's/early 60's.
Rockers: Leather clad, slicked back hair tough guys that rode motorcycles, same place and era.
This annual thing is put on by an old friend of mine. It's a great time. Lots of old bikes, loud music, big street party.
Unfortunately the guy that puts this thing on has a knack for scheduling his events when I'm out of town. Or maybe he's trying to tell me something. Anyway, I'll be racing at Grattan that weekend.
