The Macy's Thanksgiving Day Parade is marching, rolling and soaring in traditional style as police go all-out to secure it in a year marked by attacks on outdoor gathering spots.

The extravaganza of Americana made its way through 2 ½ miles (3.22 kilometers) of Manhattan on a cold morning, with new faces and old favorites in the lineup.

Authorities say there's no confirmation of a credible threat to the parade, but security is heavy. The parade comes after a truck attack on a bike path near the World Trade Center killed eight people on Halloween. Weeks earlier, a gunman rained bullets down on a crowd at a Las Vegas country music festival, killing 58 people.

Paradegoers say the ramped-up security makes them feel confident the spectacle is safe.

A balloon has blown into a tree and popped at the Macy's Thanksgiving Day Parade, but no one was injured.

An Associated Press reporter was on hand as a gust of wind carried a candy-cane balloon into a branch around 10:30 a.m. near the start of the parade route on Manhattan's Upper West Side. The candy cane was smaller than the parade's signature giant balloons.

Police quickly cleared the deflated balloon out of the way, and the parade continued.

In 2005, a giant balloon caught an unexpected gust of wind and struck a lamppost in Times Square, injuring two people. Since then, the parade has been accident-free.
