The hackathon story by @stsp is awesome. Donate to OpenBSD so they can go on crazy secluded hackathons more often.
I actually don't have the words to describe how idyllic this hackathon was.
You could sort of put together something like that in Scotland, but I doubt we have really serviceable cabins you have to hike to.
campgnd (which I run) goes some of the way, but you can just drive right up to your pitch.
I'm a 3 season camper and like to camp off the motorcycle. If it's too cold/snowy for riding the bike, it's too cold/snowy for camping . 😉
It was mid-30's (1C or so) overnight on this trip but warmed up quickly as the sun came up. 😎
