PASADENA, CA -- Authorities are stepping up security ahead of the annual New Year's Day Rose Parade.
Two B-2 stealth bombers arrived outside Pasadena, California this afternoon.
They will perform fly-overs during the Tournament of Roses Parade and the Rose Bowl game.
Hundreds of R-V's are already parked along the parade route in Pasadena, but police say the vehicles pose a security risk.
R-V owners have been warned their vehicles may be subject to search.
