Whitney Houston's new neighbors in Mendham Township, N.J., wish she would hurry up and get moved in. The neighbors on North Gate Road, which has houses on five-acre lots set back from the street, are complaining that 15 to 30 trucks are regularly parked along both sides of the road on weekdays and sometimes on Saturdays while crews install a sound studio, swimming pool and tennis courts for Houston. However, police have gone to the site several times and found no parking violations, Police Chief F. Herbert Herron said Tuesday. The 24-year-old singer, who was born in Newark about 30 miles away, has missed much of the flap because she's been in Europe since mid-April.
