> You'd note a restriction of movement -- "up" (away from the black hole) is no longer a possibility; every direction is some variation of down, perhaps down and to the left, down and east, whatever, but always down. You'd notice if you were doing calculations as you fell. Locally, nothing particularly special happens at the event horizon, as far as I understand; just, past that point, all future directions lead to the centre of the black hole. (Plenty of past directions still point outwards, so you wouldn't even see anything particularly special unless you were paying close attention to, say, the apparent shape of the black hole.)
