Bay seniors who long ago got over their annoyance with fussy Victorian architecture should pay a visit to the baroque pile that is the Boyd Museum in San Rafael. This former summer home now houses the Marin History Museum. On Thursday September 13 at 6:30 they are offering a lecture by author Jack Gibson that sounds fascinating – the history of the 22,000 acre Mount Tamalpais watershed from the mid 19th century. I guess that means no Indians. Suggested donation $5-10.
