We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember saying
something like:

Best remote fire valve I saw was in my old company. There's a fire
panel on the wall, with a big yellow button that says "push to test"

So one day a passing stranger followed the instructions, and dumped a
sizeable halon tank into the comms room on the other side.

Bit daft though, having a 'Push to Test' sign on a live trigger.

Fair made a big bang, I can tell you.

The following week, a perspex cover appeared over the "push to test"
button, with a lead crimp on it ;-)
