Q For many years alongside Interstate 880 in San Leandro just north of Washington Avenue was a sign that said: "STOP CASTING POROSITY." It was an advertisement for a product used to seal cast-iron pipes, but for years I thought it was some sort of political statement. I'd sometimes throw my fist in the air while driving by and yell, "Right on!"

Mike Kahn, Hayward

A I liked this one, too, and it was the favorite of many readers when I asked to list their favorite roadside signs. Coming in at No. 2 wasn't a sign, though. "...

Q My favorite wasn't a road sign, but the fake CHP car that used to be sitting on the summit off Highway 17. I found it humorous and miss it. ... I think they removed it due to vandalism, but it did make you slow down.

Ed King, Mark Adams and more

A Staying on 17 ...

Q My favorite roadside sign was posted several years ago and gone the next day. It was written on a large piece of cardboard and strapped underneath the huge radar speed sign at the summit of southbound Highway 17.

"HI SCORE: 112."

Peter McClure, Santa Cruz

A I hope not!

Q My favorite sign was the big Caltrans message board on the Sunol Grade along downhill Interstate 680 by the CHP weigh station:

"HANDS FREE. IT'S THE LAW."

So I stuck my hands straight up through the sunroof like you do on the downhill side of a roller coaster and yelled "WHEEEE-E-E-E-E-E!" Well, it said, "IT'S THE LAW."

John Gordon

A I would love to have seen this.

Q This was a sign on Interstate 5 at the entrance to a rest stop in the middle of the long downgrade entering southern Oregon:

"BRAKELESS TRUCKS MUST BYPASS REST AREA."

Larry Koepke, San Jose

A I would hope so.

Q Driving south on I-5 past the Oregon border is a huge billboard that says "Enjoy Weed" — meaning the city. I couldn't believe my eyes.

Kathy

A An online chat person said an octogenarian member of her church made the mistake of wearing an "Enjoy Weed" souvenir T-shirt on a weekend in Las Vegas and got a lot of kids saying, "Rock on, Grandma!"

Q I saw my favorite sign on a visit back in Pennsylvania near several stop signs. Sure wish they were out here.

"COMPLETE STOPS FREE
ROLLING STOPS $108
YOUR CHOICE."

Carol Hanson, San Jose

A We have our own variations....

Q I love this sign in Redwood City near Arguello Street:

"SPEEDING TICKETS
AVAILABLE AHEAD."

Linda Shepherd, Los Altos

A And ...

Q I have a favorite parking sign at a preschool on The Alameda near Park Avenue, advising:

"CARS MAY BE FINGERPAINTED."

Liz

A I bet this one brings a smile to many faces.

Q I like the signs on Shell gas stations, when the lighted "S" goes out.

Vern Patterson

A A favorite gassing-up place for the Hells Angels, maybe?

Q My favorite road signs are of frogs, maybe 6 or so, along Interstate 80 near Davis. I believe they are for a real estate agency, but I just love the frogs. The last time I went there weren't as many of them. Made me sad.

Suzanne Willis, Santa Cruz

A No longer jumping for joy, eh?

Q On I-880 in Hayward there used to be a sign saying:

"A STREET DOWNTOWN."

I always got a chuckle out of that one.

Harold Hall, San Jose

A As did I.

Q My all-time favorites are the billboards and truck ads for Clover Milk. Their advertising department is so consistent with Clo, the Clover cow, and always giving perfect one-liners. The latest as you exit Petaluma on 101 is yet another classic. Clo has a big smile on her face with the caption:

"GO AHEAD.
MILK MY DAY."

Jone Manoogian, Palo Alto

A Can't moo, er, boo, that one.

Q The best sign is on 101:

"IT'S HAPPENING
IN SOLEDAD."

It kills me every time I pass it. ... I've been wondering all these years what's happening in Soledad.

Mike Dominick and Ted Williams

A Me, too.
