Wow. That is incredible. I've been mistaken as the 'feeder' and surrounded but never felt threatened. Maybe it's cause I grew up working around and with cows? Jeeze, from the time I was walking practically I'd been around cows. Only the odd bull would be threatening. My Dad and his partner bought a bull at an auction sale that they sold less than a year later. He was just a bad actor and neither of them wanted him around.
Interesting circumstances. Glad you got out safe!
