Years ago when hunting Maine and before treestands were popular, I would actually sit high in a big pine tree. I was very successful in tagging. Since those days of yesteryear, I now either use my lock-on or my climber in both Maine and NH and will sit from dark 'til dark. Sure there are times when it gets rough, especially when the weather doesn't cooperate. I love watching the woods from 20 feet and I continue to tell myself that the longer I stay the better my odds 'cause sooner or later that big old bruiser will show himself and never know I am watching his every move. Any yes, I'm an old far* and now hunt not only with my sons but also two grandsons.
I think my style, although successful even for New England, may be my biggest fault. I am stubborn to move. A friend suggested I try the "three sit" strategy, with each "sit" being 1/2 day hunt. He says to move after three sits to a different location if I don't see deer. It needs only be a few hundred yards or even much further. I guess the idea is to relocate with the hopes of seeing more deer. I just might try his suggestion but then again, like I said I can be real stubborn...
Good Luck to all this season......Jimmy
