trained there myself, back in the '70's...helped erect that fence around the installation for the Cubans that Carter was letting into the country...the folks in Toma and Sparta were pretty pissed...
I missed that period--was done and gone mid-1975. Was back once, with a Boy Scout troop. We took a winter camp up there (you can do it, making arrangements in advance)--and picked a weekend when the BlackHawks were exercising. The kids were awestruck.
Also happened to be an infantry/gunnery company on base, so we took the kids out to the range and they watched .50Cal machine gun barrels turn cherry-red.
