What a gift! Milwaukee boys and girls get amazing holiday surprise at abandoned Northridge Mall

Casey Neistat's surprise

MILWAUKEE -- YouTube star Casey Neistat shined a holiday light on Milwaukee's abandoned Northridge Mall in his latest project. But he could not have done it without the help of dozens of kids from the Boys and Girls Club of Greater Milwaukee.

Neistat, along with help from Samsung, got the kids to help him create the holiday video. But not before he and a team of hard-working elves turned the empty mall into one amazing winter wonderland.

The kids had no idea what was about to come. But the special surprise involved a sled run, candy, snowboarders, ice skating, carolers and even the jolly old elf himself, Santa Claus.

It's a pretty sure bet this is one Christmas surprise the children will not soon forget.
