For all intensive purposes Oak Park is suburb/village area (same with River Forest) is within the greater Chicago area. They may have their own specific town setup and like the sense of independence, but basically is engulfed in Chicago in a similar way to Speedway or Broad Ripple have with Indianapolis. If you prefer by or right outside Chicago though, I guess I can go that route.
But yes, a super power house team with most of their starters in the national rankings or at least honorable mentions. Penn will definitely have their hands full. If I recall correctly Carmel wrestled them at an event last year.
