semo - I was at Great Lakes from 9/87 to 7/95, so visited NAS all the time during that period.
I remember an enormous wooden structure, like a hangar, that stood between our building and the ramp. It had basketball courts and other MWR-associated activities in it, and on the long walls of the building, on the 2nd floor, there were offices. It had a beautiful planked hardwood floor. If during your tenure you ever went north to Waukegan/North Chicago, there were several identical buildings at the NTC, across 22nd Street, that greatly resembled that building at the NAS. At NTC these buildings were used as cold-weather drill halls and for instructional purposes. It may have been what the building at NAS was used for as well, during WWII. I think the one at Glenview burned down in 1989 - 1990, can't remember the exact dates, but I know it burned. What a loss.
