A Cow's Tail

I have a story about a cow's tail or tails but it really should be tales.  On Wednesday, as I was working away in my Crafty Cottage,  Tim and George claim that about 30 cows came into the orchard in the corn fields or where the corn was planted last year.  The border of the farm is surrounded by dairy farms and an occasional cow has wondered into the orchard.  30 cows have not.  George called the local farmer thinking they were his cows but when he came over they were not.  It turns out that the cows came from a farm that is next to the farm next to us.  That farmer came over and worked the cows back to where they had broken through the fence.  Here's the thing, in a world of technology and everyone with a cell phone was there one to be available to prove this story correct?   Of course not but they claimed it happened.  I guess the cow patties and hoof prints can prove it BUT I don't have any pictures.  This cow's tale did happened!
