Cleveland celebrates first title in 52 years at downtown Cavs parade

So this is what a celebration 52 years in the making looks like.

An estimated 1.3 million Cavs fans lined the streets in downtown Cleveland to celebrate the Cavaliers' first NBA title, which is also Cleveland's first title in any sport since 1964.

And the city was packed to the max, as caught by those in attendance on social media.

Not to be outdone by the fans, the players joined in on the fun too. LeBron James celebrated worry-free with his family.

Kevin Love repped the WWE.

And J.R. Smith, well, he continued his shirtless trend and celebrated with throngs of fans.
