My Aunt and Uncle had a pretty extensive farm in Illinois and my family used to visit them in the summer quite often.

They had a bunch of cattle in the timber that were almost closer to a wild herd!! They also had a barn full of hay or straw bundles that the cattle had access to.

My little brother and I had a jolly time teasing the cattle{we had much more respect for the hogs, and one particularly nasty half blind rooster who thought that he were the elected barnyard tyrant)But we'd pick a cow to tease and then run for the barn and up onto the straw. My Uncle tolerated it, but my Aunt heard the ruccus and put a halt to it so she wouldn't have to send at least one of us kids home with serious damage. It was fun while it lasted, but it was scarry fun as even an ol' cow could run a whole lot faster than even we super-quick little guys had expected!!
