Back in the 1980s I was crewing for a woman training for RAAM. As we approached a certain corner on a backroad leading to Cajon Pass I radioed to her, "Watch out around this corner for motorcycles flying across the road." She laughed. Around the corner a large machine did go over the road some 10 feet in the air, 20 feet in front of her. "I thought you were kidding" she said. "It is a dedicated state area for dirt riding and I've seen it before" I told her.
