Rockets and Roman Candles are no good either, giving off choking, impenetrable smoke. :yucky:
A lad called Simon Monk let some off in between the first couple of pitches in Tathams Wife Hole (Yorkshire) around 1985 on a Leicester Poly Caving Club trip. :spank:
At least 10 years latter some LPCC members met a group underground in the Burren (Ireland) and the usual pleasantries were exchanged. As soon as LPCC was mentioned, the group became agitated and demanded to know if any of the LPCC members was Simon Monk.
It turns out that they had a group further down Tathams Wife on the day of the fireworks and it had become club folklore that they should massively damage any caver they found with the name Simon Monk!
I don't think that they will get their wish though - he moved to Australia in the early/mid 90's and, I'm told, married his Phillipino maid a little while later.
