RE: How long before you decide to move your stand?
Like others have said, this time of year can be tough.
That being said, I think the worse thing you can do is overhunt a stand. This is coming from a guywho was real stubborn when it came to moving. I used to think the longer I stayed, the better my chances because sooner or later they will be coming through.
In order to be suucessful you have to hunt where the deer are. If you hunt one stand and see nothing for 2+ days, that tells me the deer are not there. Get out, start scouting again and find them.
Just my .02, but you will see and shoot more deer.
