The Sonoma County Museum’s “IMBY” exhibit is a hit.

More than 400 people attended the opening reception last Friday, Jan. 25.

A lecture about the show on Sunday, Jan. 27, also was well-attended, said Pat Lenz, one of the exhibit’s organizers.

The exhibit’s title is new take on the old idea of “NIMBYs,” the folks who show up at public hearings to say they really don’t oppose the construction of the latest big facility of some sort, as long as it’s “not in my backyard.”

For the “IMBY” show, roughly 100 photographers were invited to come into the Sonoma County Museum and take hundreds of photos probing the building’s details and hidden spaces.

The pictures they took offer a new perspective on an old and familiar building, which served as the downtown Santa Rosa Post Office from 1910 to 1965.

The building was originally at Fifth and A Streets, and later was moved to its present site at 425 Seventh St. in Santa Rosa, where it has served as home to the Sonoma County Museum since 1985.

“IMBY — In My Backyard: The Sonoma County Museum as Subject” continues through Feb. 24 at the Sonoma County Museum.

Hours are 11 a.m.-5 p.m. Tuesday through Sunday.

Admission: $7; $5 for students, seniors and disabled; free for children 12 and under.

There will be a roundtable discussion of the exhibit at the museum at 6 p.m. Thursday, Feb. 7. Admission: $5-$7.
