RE: deer fever?!?
I have killed deer for years and i still freak out over a 60# doe walking out thats the reason I hunt, but to calm down I focus on the shot and on a single hair on the shoulder.
As for the boredom factor. I have taken books but usually try to put my stand in an area with lots to view. I get int he deep woods sometimes and there just isn't enough to look at. I hunt fire breakes right now and continually scan the 600+ yards of road in detail it works rather well.
