NOTE: TICK BLOOM – We were informed of a ‘tick bloom’ on Mt. Tam, in late April 2016. If your assignment takes anywhere where you might be at risk, PLEASE TAKE PRECAUTIONS!
Date: Saturday June 17, 2017 About 06:30 – 14:30
Activity Description: Communications support for The Double Dipsea, an annual trail run event that starts and finishes at Stinson Beach.  Around 800 participants run from Stinson Beach over Mt. Tamalpais to Old Mill Park in Mill Valley, and back over the same course to Stinson Beach, about 14 miles of steep terrain.  This event has a staggered start according to age and gender.  NOTE: Some slow-moving, un-official participants may be on the trail before the event officially starts. The permit in 2017, moves the start time, forward earlier.
What will be expected: Hams staff fixed locations along the trail.  Monitor and report the first participants by bib number through a location (in each direction), and monitor the last participants progress. Report any participants who need assistance or who drop out.   Please supply your t-shirt size, when signing up. See: Double Dipsea Station Locations
Hams required: 6 – 10  Volunteers
