Ok, so this sounds stupid and obvious, and whatnot, but of well. How do you actually connect your protection to rock? (stoppers, cams, hexes, other stuff I heard but don't know what it is) I mean I understand an old fashioned Piton, drive it into a crack in the rock, connect to biner/rope or with something like an ice-screw, the name explains it, but how do you protect a pitch on a rock face?
