The rain has been falling in Northern California, if this storm is an atmospheric river, then we are in the waterfall right now. The Russian river is at flood stage, roads are closed and the mud is keeping me off the trails. In between gym time , I am planning the route. I will have to connect the bay ridge trail with fire roads or bike friendly roads. My references include the Bay Area ridge trail book by Jean Rusmore, strava heat maps, bike touring maps and ride with gps. The route is downloaded to the Garmin. I chose a gps over smartphone for signal strength, and AA batteries (important). I plan on taking paper maps and when on my bike not afraid to ask for directions.
