I hate hogs. They finally showed up on my property a couple years ago. Now at certain times it seems like I'm over run, then others they disappear. I decided to build a trap. 8'x16'. Nice and sturdy. Well my trap worked fine, it caught several. Now I have to figure out how to turn it into a trap/holding pen. The pictures tell the story. One minute the trap has several trapped hogs in it. The next minute the trap has no hogs and no door, at least not attached. It looks like they were in a huddle planning the next play. I guess the play was we stampede the door and get the heck out of here. I think the one hog just went back to get something he forgot. It's personal now. I hate hogs!!!
