a friend told me about one while we were passing by, now that i think of it it reminded me we were on a sc/out/ competition
it's on a local hill, on top of an old tower that was supposedly used for something about ski jumping, not sure
to get to it, you actually have to jump from ledge to ledge and risk serious injury, even death for fuck's sakes
i know this probably isn't the most dangerous one because there are some in really small caves for spelunkers but it's still pretty crazy, for freerunners or climbers
