I need some good locations in and around St Louis to railfan at. Thanks! P.S. Illinois isnt ruled out either.
There is a Hobby shop in downtown Dupo, IL that has an upstairs balcony that overlooks the UP yard. I believe they charge $2 admission to go up there. (Dupo is just north of East St. Louis, you get to it by taking I-255 across the Jefferson Barracks Bridge.
