The most natually thing to do after hiking was to take him drivng up the steep Berkeley hills. We found the Berkeley Rose Gardens! It's 3.6 acres of roses, 250 varieties, and roughly 2500 bushes. The terraces and gardens were built as a WPA project in the 1930's. It's pretty amazing, no wonder it's booked a year in advance for weddings.
Redwood pergolas and roses obviously
We found a snail!
