Do you mean by Mannheim Road and I-290 in Westchester?
I guess. Coming from Midway, once you get off the interstate, you take Mannheim south a couple of blocks and there's an intersection With an I-Hop restaurant a CVS Pharmacy and a funeral home. If you took that left and go a couple of miles east, the Forrest Park Wal-Mart would be to your right. Somewhere around that WalMart, if you turned left and went north, you'd arrive at a commuter rail station which I'm pretty certain was the Forrest Park station. My friends lived within walking distance of the I-Hop I previously mentioned. On a number of occations, I'd walk from their house, catch the bus to the train station and head into town. Did so during day and night and while always carefull, I was never particularly worried.
