I have an alcohol-fogged memory of setting off a green smoke grenade on the nose of a surfboard off China Beach, a couple days before I shipped out.
I was soon greeted by an Apache helicopter!
'nothin' like staring down the barrels of miniguns and rocket launchers.Very sobering!
I bought some smoke canisters years ago and in respect for my neighbors never felt comfortable setting them off.
They're probably ruined by now,exposed to the Texas humidity.
