Make sure your wind directions are correct or else you won't see anything.
What i did was make a big pile of dog food and shoot anything that came along to eat from it. Coons, skunks, anything. The animals would die there and it created a nice pile of death that attracted the Yotes. If you want to get extreme, find a dead deer and drag it out there. You'll be amazed at what a pack can do to a big carcass like that in 45min.
