Free racing cones!
 

Okay, if anyone here is subscribed to Road and Track Magazine, look for the Mini Cooper AD, there's tear-out orange racing cones with it! Sure, they're paper, and cheap, but they're large, uniform, and easy to see. If they blow away, tape them to the ground. It comes with 8, and I suggest you fold before you tear... They were originally meant for a 700-ft mini-slalom course for one of the new mini coopers, just to show off their handling.

Hahaha, I got some of those.

hehehe, must burn paper
