One of my father’s favorite jokes was to take a cliche and turn it upside-down:

“Everybody’s crazy except you and me, and sometimes I’m not so sure about me.”

Or: “Things will get worse before they get worse.”

Or, appropriate to today’s topic: “I know a lot about art, but I don’t know what I like.”

In the past week or so, readers of this blog have participated in a loose, ongoing discussion of public art.

Readers gave mixed reviews to the whimsical work of sculptor Robert Ellison, including “Donut Diorama” at Wells Fargo Center for the Arts and “Renaissance,” the giant scissors at Santa Rosa’s Old Courthouse Square.

Support remains strong for the statues of Charles Schulz’s “Peanuts” characters — Charlie Brown, Woodstock and Snoopy — scattered around Santa Rosa, especially with 30 new Lucy statues coming this summer.

And several people mentioned the Sculpture Grove at Santa Rosa’s Paradise Ridge Winery, and particularly the huge redwood sculptures of Bruce Johnson, whose current show, “Uprooted,” runs through April at the winery.

Johnson used roots, logs and copper boulders to create 11 new sculptures with titles like “Outburst,” “Rock Slide,” “Eko” and “Ion.”

Go out and take a look, at 4545 Thomas Lake Harris Drive, Santa Rosa. Information: www.formandenergy.com/uprooted, 528-9463.

Any thoughts on Johnson’s work? Or suggest some other public art somewhere in Sonoma County, and we’ll try to dig up a picture, and start a new round of comments.
