The inaugural “Relay Trail Trials,” hosted by the Relay for Life team Relay Riders, will be held tomorrow at the Gaddy Shack Ranch in Kelseyville. They’re collecting donations of $40 for the two classes and lunch. The equestrian event features vendor booths and prizes too. One hundred percent of the proceeds go to the American Cancer Society’s Relay for Life. Visit https://www.facebook.com/RelayRiders .
