I'll second the bit about dogs.I was hiking with my lad and his cousins once and we went through a field of sheep that had a couple of llamas in to protect them.They went crazy when they saw my dog and chased her right around the field,my dog bowled three other hikers out of the way to get over a stile before the llamas caught her.This was the first time my nephews had been hiking and one was so scared he was crying.......I found it funny afterwards but not at the time !!!!!!!!!
