Not sure that is a good idea due to the smell spray paint gives off even after it is dry. I would just get a cheap after season vest for a buck or two and either pin it or sew it on to the back pack. No need to give the critters and more of an atvantage then they already have.
I don't wear it to hunt. Just haul meat out after the kill.
I usually just wear a waist pack to hunt in. I carry some food, and everything I need to dress out the elk. I then carry back the backstraps and loins to the Jeep. Lock up the gun, and grab the big backpack and go get the meat. At that point i'm not hunting anymore, but I think the blaze orange laws still apply.
Jim Zumbo, Craig Boddington, Ron Spomer and Wayne Van Zwoll are all solid contributers to the modern hunting literature. Through their gifts (both hunting and writing) they make us better hunters. Whether it is letting us learn from their mistakes or by teaching us new techniques,they help us harvest more game. But I suggest looking to the oldies, the fathers of the outdoor writing craft, to learn tricks that you might have not used.
I chose to shoot the 270 winchester because I grew up...
