With a burst of confetti and fireworks, throngs of revelers have ushered in 2018 in a frigid Times Square as the glittering crystal ball dropped.

It was the second-coldest New Year’s Eve on record. The temperature was only 10 degrees (minus 12 degrees Celsius) in New York City at midnight. The coldest ball drop celebration was in 1917, when it was only 1 degree (minus 17 degrees Celsius).

Partygoers bundled up in extra layers, wearing warm hats and face masks, dancing and jogging in place to ward off the cold.

There was also tighter security than ever after two terrorist attacks and a rampaging SUV driver who plowed into a crowd on the very spot where the party takes place. The party went off with no major problems.

In Boston, it was even colder than Times Square. Temperatures were around 5 degrees but that didn't stop thousands of people from packing Copley Square.

And a few hours later, 2018 was celebrated in Las Vegas. Security was in high alert in that city as well, following the sniper-style attack from an upper-level hotel room last year. Everything in Las Vegas, went off without a hitch.
