I was there from 77-81. Thanks to the Army, I got two trips to Crete, a week in Oberammergau, and a 3 month TDY to Northern Germany, about 30 miles east of Kiel.
They had to drag me out of there screaming and kicking. For a variety of reasons, I've never made it back. Hopefully, my employment situation will improve so that we can see "The Passion Play" next year.
Never used GPS. Make my own maps if I’m going someplace for a long trip, nothing annoys me more than having to rely on what someone else thinks are the important parts!
I think my longest trip is a 4000 mile or so drive to TX and back. I had a blast. I only got lost once, in Great Falls.
