Leave it at home, from what I have heard the "Prison Issue Tissue" is not so comfortable on ones nipsey, especially if a few "lumpy farts" have passed through prior to application.
If you do decide to take some very young homebrew, be sure to pack some wetwipes for your delicate areas. As having a sore "tea towel holder" could ruin the enjoyment of slopping about in a muddy farmers field for the weekend, getting seriously rained on.
I on the other hand will be watching from the comfort of my own armchair, marveling at the excellent coverage from the BBC, sipping liberally on my favorite homebrew, then tucking myself into a nice warm bed, fully in the knowledge that some super absorbent "Kitten Soft Tissue" will be on hand for my own Sherrifs Badge as and when required.
