I know others have posted this ride, but I thot I'd add my $.02. This was one of my first rides of the season, and it was tuf on this old guy. The quality of the roads did not help. A nice wide shoulder on 246 was made worthless by all the heaves or buckles that made for a VERY bumpy ride--especially going downhill. All the hard work, for me, pedaling uphill was lost by braking on the way down. Let some air out of your skinny tires if you ride this. Santa Rosa Rd was not any better, but it's a county road---so---- The scenery was awesome---worth the ride. Temp was above 80 for most of the ride, and coffee & lemon bar were great at South Side Coffee. Thanks to other posters for this.
I rode some of 246 east of Buellton and i'd say it was a perfect road--wide, recently repaved. It was littered with small pebbles but that's to be expected this time of year.
