As I remember CIRCA 1964
The Drill Hall had many line-shacks that were sort of reservist maintenance
divisions on weekends.
The Marines worked the Boxcars (C-119s/ R4Qs) from there and most of the
floor space was used for SH-34 maintenance.
Most of the duty that I pulled was line duty and I stayed in a "Line Shack"
where there was a huge military radio of some sort that could dial up almost
any distant AM radio station. This was a most lonely and remote place from
midnight to 0400 (4 AM).
I think that the huge laminated wooden arced beams there, might have been
some of the largest ever made.
