This may be too little notice, but I wanted to see about doing a drive next Saturday morning from Fremont to Livermore via Calaveras and Mt. Hamilton. The forecast shows it should be sunny and warm, and based on this year's trend, I wouldn't bet too hard against it.
My thought would be to meet at the Peet's Coffee at Mowry & Paseo Padre in Fremont at say 7:30 and leave by 8. Make our way up Niles Canyon to Sunol and over to Calaveras. We'd follow Calaveras up and around back toward the valley and skirt over to Mt. Hamilton RD (I'm not confident of any roads connecting the two without heading back down for just few miles). Mt. Hamilton will connect us to San Antonio Valley and up Mines to Livermore.
With a few stops along the way for photos and maybe check out the observatory, it figures out to about 4.5 hours (3.5 driving) according to Google. I'll see about sorting a lunch spot in Livermore.
If we want to get on the road earlier, we can do that too. I'll have my son with me for his first group drive.
Anyone interested?
