down town st louis is the site of the all star baseball game this year. there is may things for baseball fans to do. last night there was a concert by Sheryl Crow and Elvis Costello that was free, held under the arch. This is the entrance to O'fallon's stadium.
O'fallon's minor league team is the river city rascals. Nice stadium, very family friendly and you are close of the action. big playground for the kids, and reasonable prices.
