I am an all-day hunter most of the time, come heat, sleet, or whatever. I could list 100 reasons why deer might move even when they want to be bedded down, and vice-versa. Weather certainly plays a part in deer movement, but my theory is that you spend every minute you can in the woods.
When you're not seeing deer, especially in a good deer area, it is discouraging. Something I try to do that helps me alot is change my perspective. Every hour that passes without seeing deer increases the chance that you will see deer the next hour. In our minds the opposite occurs: every hour without deer makes us think we are not doing something right or that the deer have changed their behavior. Odds are we are right where we need to be, but our roll on the dice has not come yet. Keep rolling the dice and your number will come up. Stay at it, and sooner or later things will have to change for the better. :grin:
