Reminds me of a couple stories about design. Many of the roads in in early America started as animal paths, because animals aren't stupid, and will take the easiest route. Animal paths got worn down more when people started following them too, then horses, wagons, etc. In some places, the only difference between a deer/cow path and a road is the gravel, or blacktop that was added later. But the route remains the same. There was a university that was planning to put sidewalks crossing their central commons. Someone said, "Lets just wait a bit on that." They waited to see where the students would wear pathways in the grass. Then they laid the sidewalks on those pathways. And there was great rejoicing. "Ode to The ALCAN Highway" - Winding in, and winding out, leaves my mind in serious doubt, as to whether the lout that picked this route, was going to hell, or coming out.

RTFM.
