There are also products made for scuba diving/snorkeling that are excellent in keeping the mask free of fog. They're inexpensive, maybe something like that would work. I've used the following Sea Gold Anti-Fog and it works well: http://www.scuba.com/scuba-gear-54/028053/McNett-Sea-Gold-Anti-Fog.html
The trick in using this gel is to apply a good layer, then quickly rinse with fresh water, and it leaves a crystal clear film that does not fog.
Also, in a pinch, I've been told that you can simply spit in your mask, rub it around and that will keep it from fogging. Divers swear by that, but I have not tried. Maybe spit on your cam & let us know how it works?
Hunting is not usually a pursuit where instant gratification abounds. It takes a lot of time, practice, resources and patience to be a successful hunter. So when someone decides that an area they hunted only once without taking an animal is worthless and devoid of game, I don't quite understand it. These people usually jump from game management unit to game management unit; trying a new one every year.
Now don't get me wrong, there are people that just enjoy scouting and hunting...
