My host Harriet is an architect.
So it was a duty for me which I loved to look at the houses and she was so kind and gave me a ride to see quite different kinds of houses. She was my oldest host, born 1925 (p.s. and I am still in contact with her and it is 2016 now)
If you want to see her houses, than enjoy I like her style.
And now more of the houses and buildings in and around Petaluma.
