Was at a FFest somewhere, Cleckie I think, last year & there was a big spotlight on a trailer parked in a remote area of the campsite.
The spot was only on at night & didn't light any useful parts, seemed to be focussed on the treetops.
The very noist generator was on 24/24, so we couldn't have a decent twang/pluck/squeeze/wail session.
I got really cheesed off, so went over to investigate offing it.
Being unfamiliar with where the stop button might be, I pressed my index finger against a likely looking object, only to find it was red hot! OUCH!!!
Eventually found the off switch & did the biz.
Was pleased I'd accomplished mission, but on me way back to our settlement noticed me finger was stinging madly & on examining it found on my fingertip a clearly indented pattern of the metal mesh I'd accidentally pressed! OWWWWWWWWWWWWWW!
Also it made holding me plec quite painful - revenge of the 'Jenny' - AAAAAAaaaaaaaargh!
