The American Farrier's Association has an update on their web site with news from a few of their members who live in the area.
National Geographic has a nice slide show of human evacuees and their animals. The photo in this post is part of that show.
Tonight I spoke with Mark Silverman DVM of San Dieguito Equine Practice; he described the scene at Del Mar racetrack as "amazing" both in terms of the volunteer spirit and the outpouring of support and supplies available to the horses encamped there--and their owners. He was treating a few minor injuries and respiratory problems but said the horses were in good shape, overall. A week from now, Dr Silverman will be in West Palm Beach, Florida to speak at the Fourth International Equine Conference on Laminitis and Diseases of the Foot.
