Answer 2

Ft. Sill is a pretty big place. What part do you need? Do you want the main gate? Headquarters?

At the intersection of Thomas Street and Blair Road, the coordinates are 98 deg 24 min 19 sec West Longitude, and 34 deg 39 min 4 sec North latitude. Is that close enough for you?

(I believe efferell01 is 1 degree too far north on his runway which would put it north of Interstate 40.)
