There correct about moving your stand.I seldom hunt the same tree twice.There are exceptions.Some are just in the right spot to work year after year.Yours must not be.If you see deer using another area regularly move over there.The best chance you have at killing a deer is the first time you hunt a stand.Sure it's alot of work,but being able to adjust to changes is what will put meat in your freezer and a rack on your wall.Sometimes hunters make things to hard.Deer hunting in general is not that hard.Deer need three things,food water and cover.If you see lots of tracks going into thick cover they are doing it for a reason.It provides food and bedding.They can bed there during the day,move around and browse and not wonder to far away from there cover.Do be afraid to move back in away from that field.The deer are there someplace.Just think of the thickest,nastiest place they could go,and then looks for lots of tracks going in and comming out.And always hunt the wind,and try to avoid walking on the deer trails.Good luck.
