Like wolfen said, you will only find does and immature animals at bait sites during daylight hours, and that is usually right at dark.
I bait and I had a 130 class 8 pt at my bait pile on opening day last year. I didn't get a shot at him but he was a dandy
I hunt an area close to my house that's only a couple of acres. The deer don't normally use it and I don't have the option of moving to where the deer are so I bait to bring them to me. I do the majority of my hunting the "traiditional" way but I do bait some also and trust me it's not exactly leading lambs to the slaughter. When they come in they normally stage down wind and don't come in until after dark and they are extremely nervous. I don't kill very many this way for those reasons. But it beats not hunting and it beats setting on my stand and not seeing a deer.
