Yes, definitely the end of an era, Tony. My condolences.
I have a nearly-28 year old mare, Sooner States Melody, a daughter of Tattoo, who I've had since I got her from R.C.West at SLJ in summer of 1985, when she wasn't yet three(but already had a foal at side). She seems hale and hearty still; is in great shape on a senior feed and tiny alfalfa pellets. She was my best-producing broodmare, and I dread the day she passes, as I love her dearly.
Again, so sorry to hear your sad news.
Margo
