I can see why you might be a little frusterated but I guess I look at it diffrently then you. I just love being in the woods. Sitting in a tree freezing my you know what's off makes it worth while to me. Bagging a deer or good buck is just iceing on the cake.
You're seeing deer and that's 50% of the challenge. You've got some shot opportunities and that's also part of the game. I'm willing to bet that the third time will be the charm for you. I'm expecting to see pics with a story very soon!
