That's the best part of hunting IMO. I love letting the little ones walk by me 5 yards away during archery season. There is nothing cooler than seeing how they act. Especially like you said when they know something is up and they are looking for you.

I was climbing up my climber this year. I got about 8 or 9 feet up, I look to my left, and a little 4 pointer was walking my way. My camo was laying on the ground because I didnt' want to sweat while climbing. This little dude is heading directly for me. I knew I was going to be busted any second being not very high in the tree and sticking out like a sore thumb. Long story short, he hung around for 20 minutes sniffing everything in sight including my tow rope, bow,and gear laying on the ground. Couple times he'd get a whiff of something that freaked him out and he'd take a few hops backwards real quick and look around. A couple of times I was looking at him through the platform of my climber. The whole time I was just hugging the tree laughing my butt off. Cool stuff indeed.
