I remember a time I was sailing at night around the plains. I think I was in mountain-level gear, and probably 25 health, since I'd sailed all day and into the night. I ended up going down a dead end channel, tried turning around and got beached on a sandbar.

I almost immediately got noticed by a group of 4 fulings, who promptly broke up their pow-wow to come give me a hand... or a club... or a spear. I didn't stick around to see.

So, now I'm running around the plains at night, underdressed and unfed, with 4 fuling at my back and who knows what in front. I see a mountain ahead, and head for that, thinking even a mountain at night would be better that where I was.

I don't remember how that worked out. Maybe I've mentally blocked it, but I would not recommend it.
