Sunrise is at 7:06. I get in my stand at 6:40.
Try getting there are 6:00 instead of 6:40. I like to be in my stand (when I hunt mornings) at least an hour before first light.
It is about 85 degrees here.
Find water and hunt over it, find bedding areas and hunt over it. Right now it sounds like the dee are going to be moving as little as possible due to the heat. They're going to move early in the morning and just before dark when things start to cool down. Either way they're going to need water eventually.
I have to walk through 100 yards of dense woods.
Try coming in a different way. If you have to go a 1/2 mile out of your way to go around where you usually do, do it. Leave early early in the morning, wear light clothing, and go around the back way.
I make a fair amount of noise walking in.
If you leave early enough and walk slow enough you shouldn't have to worry about a little noise spooking deer. It sounds to me like you're sleeping in, getting up, and rushing to your stand. Don't. Go to bed early, get up early, move slowly.
I do not know what I am doing wrong but I am doing it.
It's called hunting, Zak. No one claims it's easy. Whoever told you that you would see deer everytime you go out didn't know what they were talking about. You aren't hunting on your time you're hunting on the deers' time. They come when they want to, not when you want them to. All we can do is set ourselves up in a position that the deer are likely to come into.
