If you think bison tubes are tiny and evil, then what are you going to think of blinkers? :-)http://cacheopedia.com/wiki/Blinker
Yeah, those are a bear, definitely a metro type setting thing, can't imagine looking for one of those in the woods. It recently, took me 3 tries to find one downtown (MPLS) that was in plain site.
On the same note, I just picked up a couple on Ebay and I plan on sticking one across from where I work. figure we need more downtown, gives people something to do at lunch.
