look on the bases of trees for mud rubs, hogs like to roll in the mud then as it dries they rub against trees leaving mud and smoothing some of the bark, thats a sure fire sign of hogs. also look around for rooting, depending on the number of hogs it may be about the size of a deer scrape or could look like a big Dozer went thru a field. others may be able to say more about what to look for, but thats the main things i look for. hopefully one of these days we might can get together and do some public land hunting, i like to do go after deer season as there is a lot less people, and i can still use my muzzleloader as they are legal small game arms.
