The FRIENDS: In the ’80s, there were boomboxes, big hair and music videos on MTV. And there was the crew that helped not only build, but ride, the trails that would become Phil’s. Builders cleared the way for informal crews such as the Black Rock Riders (shown) led by Phil, Bob Woodward and Dennis Heater (center, with a bike overhead). While the Sony Walkman may have given way to Bluetooth, Phil’s Trail complex rocks on as an icon in the mountain biking world.
