Of all our horses, Cali is the most relaxed around people. We are hoping she'll be a great horse with the grandkids! She isn't as big as Sunni, Beauty, or Gigondas and she is unspookable. She's very laid back. I've never seen her take off in the arena like Beauty or Gigondas or Sunni. Hmmmm....our two mustangs seem to be the quietest and calmest of all our horses!
