RE: How many already know...
In NJ I have an idea, but it will be determined by the wind as to which actual stand I am in. No way to know that until the night before.
In PA I may have a dilemma. My 15 year high school reunion is on the evening of the opener so I'll have to be in the Pittsburgh area at that time. I may stop in to my rifle camp if its open and hunt a saddle on a ridge leading to a bedding area. If it's not, I may have to wing it and hit one of my old haunts and hope the deer still move like they used to.
