ah bidet was just known as ‘bidet’ or ‘vcr’ (there was one of them on the preceeding corner before the bidet turned up) to us but I like bumwash 🙂
we kinda use the name after what you found method as well sometimes, with ‘cooker run’ (AKA hobnob), the one that had the cooker top hanging off a tree at the split from barking dog.
Rat Run did have a sign up for a while, no idea who put it up but it was known as rat run to us before that, like how that trail evolved so many times too eventually splitting and morphing into Harveys before the red run went through it.
There’s loads more but I cant remember the names as was getting on for 13 years ago now before the marked trails were there, only one I can remember is ‘Baja Freeride’ but pronounced ‘Badger Freeride’ the end of which is kind of still around but cuts through the Blue route in the half height Xmas tree area.
I love trail naming amusements, do you ride woodbury too? do you know ‘the rooty climb of rooty b4stardness?’ I can see no other way of naming that one!
