RE: chewing or dipping while in the stand
It seems that if the deer in your area don't associate the smell of chew with danger then it won't spook them. Once they know that smell is associated with a camo blob in a tree then it will spook them. It's nice to have a dip to help pass the time. When I dip in the stand it makes me wonder if I would have seen more deer if I didn't dip that night.
