Nice shots man. Some of them you need to slow the shutter down to get the wheel movement.
I too also need a telephoto. I was just thinking who I know around that shoots Canon but didn't know anyone. Maybe we would trade lenses for shoots. I have a Tokina 10-17mm fisheye and also the Canon 50mm f1.8. You could borrow it when needed if you picked up a decent telephoto. Also check out www.rentglass.com. They are good people. And you can pick it up in Celebration and ship it the day before it has to go back.
