Back in the '80s and early '90s both my Dad and I were lucky enough to tag bucks large enough for us to qualify for the Maine Big Bucks Club which requires a buck to field dress at at least 200 pounds on a certified scale. My Dad's tipped the scales at 217 and mine was 225.
Also, I didn't notice any mention in any of those links of Maine's all-time heaviest buck which was taken in 1955 by a fella named Horace Hinkley and weighed 355 pounds on a certified scale (if memory serves me). Most sources say this is the 2nd largest whitetail buck ever recorded (dressed weight) with only a large Minnesota buck weighing in more, dressed (again, if my memory serves me).
If you're lucky enough to be on private land and can leave your stand up during the off season you can tie an old piece of cloth or something of the sort to your stand. I like to use an old camo bandana that I have. That way the deer get used to the movement and eventually don't bother even looking up when there is slight movement. This may just give you the time to draw your bow or raise your gun without being detected.
