CHICAGO – The Chicago Department of Aviation is looking for a few good goats.

WFLD-TV (http://bit.ly/Ns4U4S) reported that Chicago recently put out a bid for someone to supply goats to trim the grass at O’Hare International Airport. The bid also calls for a goat herder.

Amy Malick is the department’s point person for sustainability, and she said the city is looking at a pilot program of 30 goats to eat grass and weeds in one hard-to-mow area. She said the area is outside the security fence, so there’s no danger of goats straying onto the runways.

Malick said the department also worries about pollution produced by mechanical mowers, so they’re turning to the four-legged variety.

Atlanta recently started a similar effort, and San Francisco has been using goats for years.
