I lived in the area my entire life until 4 years ago, watched Ft. Ord get converted to civilian use, blah, blah, blah. Drove through it every day for several years - there was a sign that read "Bayonet Briefing Room" with an arrow I used to see. Near the 12th st. gate (Marina side). Always wondered what that was all about.
What was up with your 1SG?
