'70-'71, I lived in Building 500 Chibana (above top). That Building no longer exists.
While there, I worked as a US Army Sentry Dog Handler. US Army no longer works Sentry Dogs.
Sentry Dog Platoon was part of the 267th Chemical Company. Late in '71, the Chemical Company moved to Johnson Island.
Moving the nerve gas was called Project Red Hat. I was one of the 220, or so, original Red Hats. Since then, that Nerve Gas has been destroyed. The Company disbanded.
Things continue to evolve, but you can still get a taco at Charlie's. Though, they've moved since the last time that I ate there...
