I tried that using the soft, malleable qualities of the snack as reasoning it would do fine in my pocket. Alas, it didn't last very long once I started going through colostomy crawl.
The Linnet Inn in county Fermanagh is across the road from Boho cave, and has a wee room decorated entirely with stone rubble in a sort of cave homage. Not the closest to a cave by any means, but the best guinness-quality-to-cave-proximity-ratio by a mile
I did some absolutely miserable SRT in one of these and didn't notice anything untoward yet. Will keep an eye out. Bit worrying when I bet most people (me at least) go for a superavanti as it's bog standard reliable kit.
I like to have surveys if I'm trying to navigate anywhere, but in this instance I had none so I was essentially leading people on a blind dander round the cave. As such I seem to have missed all the fun bits I was told to see.
Anyway we mostly went in a straight line until the trip ended at...
