I was on a permissive TAD trip to Washington D.C. to run the 1982 Marine Corps Marathon. There were about 20 of us from Camp Pendleton who were running in formation. We flew cross country in a C5. A very impressive aircraft I might add. We got into ? Dover maybe ? It's been a while, but the Air Force put us up for the night in a nice barracks and fed us in a superb chow hall. I was always somewhat jealous of the perks that the Air Force has.
