Yeah, feeders work great unless you have the pigs like we have. Or if you put them out 2 weeks after the season starts and they spook the deer like I did, boneheaded move on my part but its staying there now (hopefully they will eventually get use to it).
I've tried the grunt and bleat calls but never had any success with them. Others I know say they work. I did get a couple of does come running to a fawn in distress call I had years ago, but that's the only response I've ever gotten.
