According to professional animal trapper James Dean..."This time of year, with the weather changes and the rainy weather, they’re basically coming out and feeding and gorging themselves to get them fat for the winter".
Please keep in mind, hogs are aggressive.. He also went on to say "They can kill a child easily they can cause a fatality with car accidents"...so please be careful if you see one. DO NOT try to approach it.
Best thing to do is to call the Police is you see one.
