I will start in late August. I have spots that are good because of terrain, I get those hung early so I'm not spending time in season. I don't do anything special, anymore I just like to wait for a nice cool morning or evening after a cold front comes through. Those stands won't get hunted til the first week in Nov.
Once I see how the mast is looking, I'll hang some more stands in September for some early season hunts.
The rest of my stands get hung based on in season sign and movement, many times I'll hang and hunt the same day.
