Having been a member for a fairly short time, but slowly making my way back through the postings, I came across this one from someone in the UK.
I am supposing the Marquee is being erected on the local village green or similar, with a dog as company and four others as back-up, I fail to see why a PSK would be needed, FAK perhaps, and as the local "Plod" will be in contact, I would suggest that the only other 'gear' you would need would be your MUMMY !!!!
Seriously, the forums are generally of great interest and it is disappointing to see it trivialised by questions like these.
I apologise in advance if I cause any controversy.
