Apparently Jack only hates fake horses like this.
Because once we put him on a real one at the rodeo last week, he loved it. He smiled and waved to everyone the whole time!
P.S. I've talked to Harrison once in 2 weeks, and have received 1 letter (and I am told there are more coming...) He is doing so well, and showing up all the other Cadets, I'm sure of it. 10 more days until we get to see him again.
