Me too I called in a whole herd......the scray thing the bull came with the cows and then went into a bellering match with a bull across the road in the adjacent pasture.....both would charge at each other but each would stop short of the wimpy electric fence.
I was more worried the cows where gonna chew on my blind....
and too bad too - that fence line was a huge big tom travel route.....but the cows would not leave me alone....I'd yelp and they come running.
