The Bird Solution

Germans have this thing about balcony areas, over-hangs, or any place where a bird can land. They hate the bird crap that remains.

So they've devised these 'nail-like' devices and put them up in the millions.  Birds don't land anywhere on that overhang, period.

I stood a month ago at a renovation project at some downtown area and watched the guy place the nails.  A whole side on a building can be done in thirty minutes.

I guess it works....you just don't see this kind of stuff in the US.
