Looking to relocate to the Chicago area and need some intel on the facilities at the Great Lakes station.

Would appreciate help from any current military/retired types who have used the Exchange, Commissary, Marina, Golf course, Gym, etc. I'm retired USAF (don't hold that against me Navy guys!), and current airline driver.

Grew up in Aurora and have family in Mundelein so I'm fairly smart on the local area but have never been to Great Lakes.

Any advice appreciated, Thanks
