Chelsea to marry 6pm EDT

Chlesea Clinton, the only child of former President Clinton and Secretary of State Hillary Rodham Clinton, will marry 32-year old financier Marc Mezvinsky at 6 p.m. EDT at an estate on a rolling country road just outside this community of 8,000 people.

On Saturday morning, several police sport utility vehicles were guarding the unmarked entrance to the estate, Astor Courts, backed up by "No Trespassing" signs. A "no-fly" zone will take effect later to protect the venue from aerial intruders.
