Caused on Opening Day. When the hunters, in the first couple of hours, realize they forgot one of their favorite electronic gizmo, and stir up the neighboring deer, by moving out of the woods to get it.
That's why I push, drive, set around lunch time. Find a nice spot and stay put from 9:00 to 11:00 move to different spot and set again. Best time in some areas are when the kids get home after school on a nice day. Or guys get home after work.
