Oak Park, IL
I currently live in Oak Park, IL. Home of Frank Lloyd Wright and birthplace of Ernest Hemingway. It's the first suburb due west of downtown Chicago. I lived here for a few years, then moved for a while. I just moved back and am so thrilled. This is my favorite part of the Chicago area. I grew up in Lisle, IL (another suburb further west) which isn't nearly as exciting.
