I am so glad she got to ride!
When my husband's great uncle was 87 years old, he rode my horse. It took both me and my husband to get him up on the horse. He didn't let me lead her, and he actually asked her to canter. Scared me to death, but he rode her great. After about 10 minutes of riding, he wanted us to help him get off. He said, "If I fall off and break something, everybody around is going to be saying 'that old fool should have known better'". He lived to be 100. He died peacefully in his own bed, at home.
