What a great report!
DH and I rode the Asti Tour de Vine last month. which started in Cloverdale and went around Healdsburg; we saw a few tour groups when we were down around Healdsburg and I'm pretty sure Undiscovered Country was among them.
I wonder if we crossed paths that day? This was on Sat Oct 15; although it looks like that might have been the day you arrived in Petaluma.
You picked an excellent time to come out here, nowadays it seems summer in our region is Sept & Oct.
