The town board of Huntington, Long Island voted to ban the sale of Silly String within 1,500 feet of parade routes because the stuff stains the finish on their fire trucks.
But at our Parade, Silly String is a time-honored tradition. After all, our floats are biodegradable. What can a little bit of polyisobutyl-methacrylate and sorbitan trioleate hurt? I'm askin' 'cause I don't know.
You ought to read the Wikipedia article. Silly String has some interesting uses. And did you know it's banned in Hollywood on Halloween? It takes a lot to get banned in Hollywood on Halloween.
Well, shoot. I was going to go dressed as a Rose Parade attendee this year.
Update as of 12:04PM:
Pasadena's Public Information Officer, Ann Erdman, corrects me even on weekends! (And I'm grateful.) She says:
"Silly String is actually illegal along the Rose Parade route, and at other special events in the public right of way, but enforcement is difficult because officers can't be at all places at all times and they often have bigger fish to fry.
Title 3, Chapter 3.22.020 (Interference with Special Event Prohibited) of the Pasadena Municipal Code reads, in part: "To drop, roll, throw, toss, squirt or propel any gaseous, liquid, semisolid or solid substance or object toward or among the participants, vehicles or animals in the special event."
Read tortillas, marshallows, Silly String, etc."
