Last Chance Rock

I used to rope swing into the Niagra River, in fact the Fly's older brother knows it as well. Its about a twenty to thirty foot drop at its highest. The water is swift and the water is dirty (Love Canal run-off) but more importantly the water is dangerous. There are whirlpools at the turn and The Falls around the bend. You get to shore no less than twenty yards from the point you hit the drink. About fifty yards there is LAST CHANCE ROCK, if you aint to shore by then, then if the swirlies dont get ya then the drop on the rocks will, and there will be nothing to remember ya by but the photos that the Japanese tourists took on their Nikkons.
Reason I bring this up is because like most nights I was out for drinks and I found something incredibly peculiar in the bathroom. Braille. Now I cant read braille and have no intention of learning it, but my thinking is that there aint no reason for a braille sign to be within an arms length of my one eye. If someone is reading it...he hit LAST CHANCE ROCK, and next thing you know I knocked out a blind guy. And Im the bad guy? Cant we install some RFID's on these people that alerts them to upcoming dangers. Same principle as to why the hell do they have braille signs on the pillars on the NYC subway platforms and not the turnstyles. As far as he knew he was getting on the A Train
