I have two friends in town:
They are currently napping on my couch after a busy day of sunshine and fresh air, exploring two of the many parks in the East Bay!
One had a labyrinth:
With treasures at its center:
The other was near the Port of Oakland:
Both had sunshine, fresh air, flowers, and not that many other people!
Edited to add: Go read Joe's account of our day! His includes a link to a zoomed-in Google map of the area, and a bit of information about the labyrinth, which was created in 1990.
