No one ever looks up. No really. No one ever looks up.

I used to have a balcony over a very crowded alley with constant foot traffic. I would stand there quietly and watch people think they were alone in this alley all the time.

Drunk people were the best. One corner of the alley was constantly getting pee'd in so they installed a metal skirt that bounced the pee back on the pee'r. You could watch drunk people pee in that corner then walk away with a wet pant leg without ever noticing. Hilarious. And not once in the 3 years I lived there did someone look up.

In older cities it's amazing how much great architecture goes unnoticed. New York city has buildings from turn of the century with most intricate decorations and reliefs and only recently I started noticing it (in a "they don't make 'em like they used to" way).

1.) 99% of the time, the people looking up are tourists.

2.) It is really funny to look straight up at the sky in a busy street and then watch twenty other people start looking up, wondering what could possibly be going on up there.

Good idea. It will force you to slow down a bit too, which is a good thing. It is hard to look up while walking fast.
