A lot of research went into finding this place. It's not like they host a website or Facebook page. I took over 600 photos over these 4 hours and only once did a set of the big cows come charging directly at me. They usually veered off to the side. It was scary watching two large bulls running directly at you but it was worth waiting until the last moment to get away this time because I have it hanging 36in wide in my living room.
