I like the rock myself. I'm not disagreeing with you guys,but heres my reasoning. I want to find the bucks. So I set the rock out with a camera. No bucks, I can pick it up and try another area. Also knowing that it does leave residue where it had laid. So it still will be visited. My 1st year I started using these I set it on a well used trail. Never moved it. 1 small buck and hundreds of does. Following year started moving it around every few weeks and it really educated me on where the bucks were. I know alot of people use these stationary feeders and so on and it may bring bucks in. But that doesn't tell you where they are coming from. So sometimes you have to go to them.
