A hat or vest, but depending on where you're hunting I'd suggest both. I was mule deer hunting near Saratoga on public ground and there were lots of hunters so I wore both. It is amazing how quickly you can pick out that blaze orange and identify a hunter.
I'd be set up on a ridge glassing and even with the naked eye see that blaze orange moving in front of me in my line of fire. The other hunter didn't know I was there up on the ridge, but I knew he was there.
Does camouflage blaze orange clothing satisfy the Wyoming Game and Fish Department hunter orange requirement for big game hunting?
Yes, it does. Both camo and solid orange garments are legal. Wyoming law requires that big or trophy game hunters must wear at least one garment (hat, coat, jacket, vest etc.) of fluorescent orange color. Camo orange fits this qualification.
In the spring of 2007 I was the unfortunate recipient of an injury cause by a damaged carbon arrow that shattered on release of the arrow. I was in the yard going to take a few practice shots before dinner and the second arrow is the one that did the damage. That day will forever be burned in my mind. After I release what happened I made mistake #2 I pulled the tail shaft of the arrow out of my hand causing more damage.
Thank goodness that my wife was home and was able to...
