The Healdsburg Museum

You might not think a small museum in a small town would be a particular focus, but in the basement, there are archives, and if you're looking for something particular from 100 years ago... they might actually have it. They had a bunch of stuff that I wanted to find, and the people we very friendly and helpful.

By the way, Healdsburg itself is kind of nice... (it's really, really nice. You should visit there.)
