The professionals stepped into their full-body racing suits and readied in the pits.
Lawn mowers -- you know, the machine used to cut grass -- tore through a dirt course dotted with hay stacks at the Lake County Fair Saturday.
Don't be fooled by the landscaping staple. Racing mowers is a serious sport with a serious following.
The U.S. Lawn Mower Racing Association, based in Northbrook, put on the contest -- a first for the fair -- and a pre-race parade.
The fair continues with another display of speed and power: a demolition derby at noon Sunday.
