A flurry of vehicles, heavy construction equipment and workers have been spotted going in and out of Michael Jackson's Neverland Ranch.

More than a dozen vehicles, including a tractor, a cement mixer and a backhoe were seen Tuesday. One bore a phone number that rang at a custom ironworks company. Gardeners and police were spotted on the grounds.

There has been intense speculation since Jackson died Thursday over where and when a memorial service will be held. It's also not known where he will be buried.

Members of Jackson's family have met with officials from the police and California Highway Patrol about funeral services.

California Highway Patrol spokeswoman Fran Clader says the meeting was held Tuesday afternoon and "details are still pending."
