Good morning.

Today’s introduction comes from Adam Nagourney, the Los Angeles bureau chief.

It’s not so easy living up in the Hollywood Hills these days. First it was the onslaught of tourists on foot, clogging the narrow, twisting streets as they used GPS devices in search of the Hollywood sign. These days, it’s a louder and more cumbersome intruder: open-air tour vans, pushing through on roads that can barely fit one car, some with loudspeakers blaring dubious claims by the driver. (“And on the left, the house where Humphrey Bogart once lived!”)

Confronted with the anguished concerns of neighbors, the Los Angeles City Council is trying to walk a fine line by responding to upset constituents without hurting tourism, a major economic force here. (And there are few tourist draws as big as the Hollywood sign.) The council is moving to adopt regulations that would require tour operators to give patrons private headphones, getting rid of squawky speakers. And the city is drawing up a list of streets where tour vans would be banned completely.

“You’re talking about over 100 buses every day traveling the small streets of Hollywood Hills,” said Anastasia Mann, the president of the Hollywood Hills West Neighborhood Council. “Blocking Mulholland Drive and creating huge hazards. It really gets out of hand.”
