I used to train at McCoy (at that time, it was "Camp" McCoy) when a member of the 32MPCo based in Milwaukee.
EVERY time we went up there for summer camp, (around this time of year,) there was at least one vicious storm which blew through.
I learned real fast that it was much more prudent to sleep in the cab of one of our 2.5T trucks, and since I was a mechanic, that was easy to arrange.
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...
Here's a personal note about Camp McCoy:
My mother's second cousin had a brother who served in the Army and fought in Korea. He came home without a scratch, and was sent to Camp McCoy.
He was killed in a vehicle accident there soon after.
