The only one I have ever been to is Chestnut. there is a place called Alipne Vally on the wis./ill. border that may be kind of close. Villa Olivia looks like its just west of O'hare but who knows waht kind of hill it is...probly an old landfill. I think some chicago people drive up to the upper pinnisula of michigan for ski vacations. you may want to look into that. you should ask this question in the midwest regional forums.
