I quite look forward to the bothy ‘randoms’, sitting round a fire with a few people you’ve never met before and trying to patch together a conversation, the people I’ve met have always been friendly and accommodating.
Never found one to be locked or vandalised and if they are there’s usually up to date news on the MBA site.
There was a post on one of the climbing websites a while ago, some guy went to a bothy with his own idea of a tranquil utopia out in the wilderness, he got there to find it was full of wild drunks, thing is that’s it, that’s how I like bothies to be, take it as you find it, get involved in the place and have a laugh, worst scenario it’ll be full of DofE kids of Munro baggers.
If you really need to be up early the next morning or want some peace then the tents the best bet, if you want some interaction and a different style of night take a chance on a bothy.
Watch your food with the mice though, I recently heard it was the bothies MO’s duty to put mice in if there were non already inhabiting. 😯
