Those look to be some nice bears. I also see that one of them is coming in in the morning. not sure when you go and bait, but I would take a gun with you when you do if the season is open. I have walked up on a bear at the bait when I went to bait in the morning, and just happend to have my gun and my stand was up at that bait. He ran off when he saw me come in, so I rebaited the bait and got in my stand. 10 minutes later he came back. He wasn't big enought, but it would be nice to shoot one in the morning rather than at dark. Those bears all look to be shooters. The 3rd picture is hard to tell, as you can't see too much of him. the 1st and last pictures look to be probably around 300 lbs. bears are hard to judge and even harder from pictures. are you hunting around antigo?
