I love shooting feed lots... Cows are funny critters.. I was on a pidgeon shoot once and sat on the rim of the feed trough waiting for the birds. I had my shotgun over my shoulder and as I sat patiently waiting, I felt a tug on my gun.. then it started to shake back and forth. I turned around to find a cow sucking on the barrel of my gun...the amount of slobber produced in those few seconds was astounding.. and it was all over the tip of my gun.
