What: No, pigs don't fly and cows don't really jump over the moon, but horses and mules stranded in rugged terrain can be airlifted to safety, using a sling specially designed to support the animal's abdomen. Dr. John Madigan, a UC Davis professor of veterinary medicine, and Ukiah inventor Charles Anderson, who collaborated on the sling design, will demonstrate its use for a group of U.S. Army and Marine Corps veterinarians interested in using the technique for airlifting horses involved in mountain warfare operations. The sling has been used in three California rescue operations involving 12 horses and mules. When: Saturday, May 21 Sling demonstration from 8 a.m. to noon Airlift at 10:30 a.m. Where: Meet at the large animal clinic, UC Davis Veterinary Medical Teaching Hospital. Airlift will begin at the UC Davis Equine Research Laboratory. (Media must meet at the large animal clinic, because the Equine Research Laboratory is closed to the public on weekends.) Visuals: A horse will be blindfolded and strapped into the sling, airlifted by a National Guard helicopter for a brief flight over the campus and returned to the Equine Research Laboratory. Directions: From Sacramento, take Interstate 80 to the Highway 113 exit and head north toward Woodland. Take the Hutchison Drive exit and go east to the first road on the right, Health Sciences Drive. Again turn right onto West Health Sciences Drive, then turn left onto Garrod Drive. At the first stop sign, go straight into the parking lot, which is right in front of the large animal clinic of the UC Davis Veterinary Medical Teaching Hospital. Parking: There are no weekend parking restrictions on campus.
