It's just like any other day of the season. You just need someone to cover the front door and hand out treats while you're hunting.
. . . Let me take that back. It USUALLY is. There were the years I was hunting a private campground out east of Cincinnati. The owner let the local neo-pagans use it for Samhein (pronounced SOW-en) festivities. Halloween is their high holiday-- kind of Xmas and Easter all rolled into one. Zowie! Those were trippy people! One year I tipped off the local TV station that the witches were out, and there was a TV crew and a satellite truck and the 6 O'Clock news lead with a live feed from about 50 yards from my stand. The pagans were all dressed in their robes and doing all kinds of goofy things there for a while. After the sun went down, they lit a fire and danced around it until dawn. Nice bunch of folks-- little strange, but nice.
A few weeks later, I was out hunting and the pagans were there again having a drumming class. They got all cranked up, and I decided hunting was going to be impossible, so I walked out to my car. On the way, I wandered into the middle of what they were up to. It just so happened they had been worshiping the male deity and then I had appeared, dressed in camo and carrying the bow. Pagans left and right were going down on their knees worshiping what they figured must be a manifestation of Hern the Hunter or some such thing. Oy!
One of the cuter pagans came up and showed me her new boob job-- she had recently had augmentation, and I had to admit that it was a . . .er. . . quite a nice job. Anyhow, after nobbing hobs with the pagans for a bit, they decided to go back to their drumming and I went back out to retrieve my stand. Lo and behold there were a whole herd of deer lined up at the tree line watching the circus when I went back in.
Bottom line: If you want a cool deer attractant, go get yourself a mess of pagans and have them drum for you while you're on your stand.
