Now, I actually start in Aug. Don't have to buy anything. Rubber boots, rake and be done with it. It's great to get pics of bucks after they break out of the summer routine. Done it for years- you can pour water in the dirt area, or pee, or do nothing. Just made a new one two days ago. Do it in a spot that they'll visit at night- along a field edge and you don't bump deer. I've seen them get squirrely on camera occasionally though- so be careful with scent.
