Hey Clippers,
According to the weather service the rain should arrive (https://forecast.weather.gov/MapClick.php?lat=33.1338&lon=-117.1987&lg=english&&FcstType=digital) at around 10 am tomorrow. I will be at the start and reserve the right to call the ride off if there's a band of rain headed in. Otherwise I propose to ride this Rainy Day San Marcos route (https://ridewithgps.com/routes/41779217) and cut back to the cars if needed.
If there's a dramatic improvement in the forecast tomorrow morning then we can stick with Sleeping Indian.
