Why all the wigs on the road?

A Wendy's cup, Slim Jim wrapper, melted ice cream, and a wig. Are these clues or just an unrelated pile of crap in the road? Hmmmm.
My friend Lisa uploads photos of interesting flora and fauna she sees during her bike rides.
If I were to do the same, I’d have many photos of wigs on the road in Detroit and Highland Park. On a ride last weekend I saw two.
The obvious question is why?
I cannot imagine the wigs are being intentionally abandoned by the wearer. Still, I can see wanting to remove a wig on a hot, humid day, but it seems you could stuff it in a pocket or purse.
If I were to start recording the GPS coordinates for each hairpiece, I may be able to detect a pattern.
Am I sure this is not just a dead critter? Sure, that’s easy. There are no flies or odor. Well, I should say not as many flies and odor.
So now I’m thinking of starting a photo collection. I’m not sure a web site devoted to Road Wigs is necessary at this point, but you never know.
