Not new surroundings, I've been to the ranch a thousand times before, it's practically home. The horse was new to me however, to ride at least, I've lead, pet, tacked up and put people on her more times then I can count. She hadn't been ridden in a while either. The funny thing is the way she reacted to being haltered I expected the opposite of her!
