If you've ever played the videogame Tony Hawk Pro Skater, then you are thinking about how fun this rail could be to grind. It's never ending! Too bad the normal world wouldn't ever see someone skating this rail, so it's pretty much useless. Someone is going to be texting while they walk down the stairs (never a good idea, but you gotta do what you gotta do) and then they'll flip over the rail, tumbling down the stairs right into a million dollar lawsuit.
I know some guys who are so manly that they'd see that and immediately go to their truck, get a metal saw, and cut this down. They wouldn't even do a bad job about it either. They'd sand it down and make it look professional. I'm not that type of guy. I'm the guy texting and falling over it.
