Hogs can't sweat so they don't move a lot during the day. If they do they will head for water. When looking for a good spot to set up look for trails and wallers in water.
During this Texas heat, I only harvest sucklings, this way I can get them in ice easier. The larger pigs are too hard to get them cleaned and iced down in the Texas heat fast enough.
We've had some real hot days the last month, but with the rain the last couple of days, I think I'm going to try this week end.
It's supposed to rain Sat. night, so Sunday morning should be good.
If I were a gun hunter, I'd hunt at night, but gave that up years ago. I also quit hog hunting nights with a bow, when I sneaked up on a group of porkers at night looking for the pig I had shot. Not a good situation!!!! I backed out and told them to enjoy it!
Good luck
