Free: Contests & Raffles.
I am almost always in a new area, so I use mid-day to scout other locations for morning or evening hunts. Although there are not likely animals out and moving, I can check access, roads, trails, viewpoints and if there are other trucks at those spots. That usually gives me a plan A and B for the next day and I just run like that until I find them or run out of days.
Its not the daylight thats hard, its sitting out under a tree for 13, 14 hours waiting for light to come back thats hard.
