[Milsurplus] Was: Strong Stomach Needed. Now ATD questions.

[Tom Dawson]

RE: FD,

I was part way there: I used an HRO-60 that started out in the Coast Guard. 
HT-37 I used does not qualify as milsurplus, though.  Whole station housed 
in a and old shelter originally used for an MRT-9 (it has space for 3 
T-368's)  Most fun I've had for FD in years.
