"Hollywood residents and businesspeople tired of being in the silly-string crossfire every Halloween have asked officials to ban the colorful streams of compressed foam. Los Angeles City Councilman Tom LaBonge ... said the non-biodegradable foam can fall into storm drains and harm marine life, and also can endanger police, particularly those on horseback. ... Several other communities, including Santa Clarita, Calif., and New Orleans, have restrictions against the use of silly string." --Newsday, July 26
