National Hollerin' Contest - Spivey's Corner

I worked on a dairy farm in college and all we had to do was rattle the chains on the pasture gate and they would come running.
When I was a kid, my granddad would pull the hay trailer with the truck and honk the horn a couple of times once he was in the pasture and the cows would come running.

CW5 Jack Cardwell thanks for the share my friend.

Saw something like this on tv a few years ago.
