I'm not sure of any good land in Chicago or close suburbs but I do know of a great prime location that would be great access from the city.
In Bartlett on the corner of RT59 & RT20 on the south west corner is a big lot. This used to be a camper dealer but since has moved accross the street. USA 1 I believe. This is the location I always thaught about if I won the lottery.LOL
There is already a building and plenty of room for a out door track. Light poles are up on the west side with parking on the north. To the east is room for a addition.
The best part is there is no homes close by.

Just take the Elgin O'Hare west till it ends and hang a right on RT20. 1/4 mi past RT59
