It could be Bigfoot. I hear a lot of the time they don't like cameras so nobody seems to get a good pic of them.
Mitch Hedberg told me that Big foot is actually blurry that is why all the pictures of big foot are blurry.
That is without a doubt a pig, I would say bout 175 pounds. Corn probably won't do you any good it's alone and running at full speed, if it had other with it corn would help keep them around but traveling alone normally means it's a boar and if that's true it is just passing through looking for the girls. Have you ever got pics of pigs before.
