We will be heading through Chicago in a few weeks (from indiana) on our way to Ohare airport. Want to hit a few vaults or O stores on our way. I am not sure what stores and where to find them. Id like to avoid the downtown stores as Saturday traffic won't be fun. Anything on the outskirts or east side of chi town that we can hit? I like to plan this out as we have limited time. Any suggestions are appreciated.
