I already have the hat. Didn't think of posting that..
I have another theory that I will be testing this weekend. It is, with the snow cover that we now have, the blaze orange may just blend with the snow (in brightness level anyway). If coyotes are indeed color blind, the blaze orange may just show up as a light gray to them. Against the snow, it may not make a difference. Anybody have any experience with this?
Another thought to ponder too is, since deer hunters are limited to hunt 1/2 hour before sunrise to sunset here in MN, do we need blaze orange if we are hunting coyotes from say 9:00pm to 3:00 am? Deer season is technically closed during these hours? With the snow cover we have now, night time hunting may be the ticket. At least we have a chance of seeing them, even on a moonless night.
