I drive on 90 towards the city from Arlington Heights to home and notice just past Lee street they are building some new buildings and there is a BIG area of unfinished land. It looks prime for bashing as from what I can see it's mostly dirt and seems to be fairly smooth. It looks like if you take higgins rd towards O'hare it's next to the United airlines office building. I might have to check it out sometime as it's only 10 minutes from the house.
