They tried this (dangling mirrors) on a section of highway in NJ, very near to where Gov. Corzine crashed. It’s the densest forest west of the Mississippi. Lots of deer.
The deer did avoid the mirrors. BUT, because the NJ DOT had to pay union wages to install the mirrors, it was deemed more expensive to place the mirrors on the highway than to have county public works employees scrape up the deer carcasses.
Gotta love this state.
When did they move New Jersey? Great idea!
