This is the base's Main Fitness Center. Four years ago when our family was on vacation and took a day-trip to MacDill AFB, we got a tour of it. It is the largest military fitness center Dave or I have EVER seen before!!! If you'd like to see what it's like inside, check out my sub-gallery (under "Vacations") of: http://www.pbase.com/lbogan/orlandojuly_2007. We simply showed up so the boys could use some of the amenities in it, were totally blown away on the hugeness & unusual inside architecture, and one of the front desk staff took it upon himself to offer us a complete guided tour thru it.
