Activity Description: Our first public service event of the calendar year; The Ridge to Bridge (hike, run, mountainbike, horseback) event is sponsored by the Bay Area Ridge Trail Council and follows the Ridge Trail (of course) from Samuel P. Taylor State Park in central Marin south to the Golden Gate Bridge. The participants gather in the Presidio (the location of net control) and are transported by bus to the various stages of different lengths (the longest starts at Sam Taylor, the shortest from Muir Woods.) There will be 300-500 participants; radio comms will be staged at 5 rest stops including net control. Seven to ten operators will be needed, depending on the need for shorter shifts . This early in the year, windy and rainy weather may be encountered. The event starts before dawn (about 5:30) and concludes before sunset (about 1830.) Please let us know early if a shorter shift will be necessary to meet your schedule.
What will be expected: You will arrive at your assigned location at your assigned time. See duty assignments for your time. You will check in with net control and report your status. You will identify yourself to the event personnel at your site. You may expect to relay messages between the event personnel and the start. You may be asked to render assistance to the event personnel. Some operators may be asked to sweep participants from the course or be asked to hike with event personnel while they are sweeping. Radio hikers should plan to report 15 at least minutes before your bus departs. You will be released by net control depending on where your location is. Please supply your t-shirt size, when signing up. Ridge to Bridge Station Descriptions
