He's this youtube personality that seems to get lots of views by filming stuff. Samsung paid him last year to film a promo video.
I'm guessing this is going to be a electric skateboarding thing but who knows. I used to hang out at this mall as a kid. Here's the Wikipedia page: https://en.wikipedia.org/wiki/Northridge_Mall_
It sits back about a block or so from the corner of North 76th and Brown Deer Rd. It's a mirror image of Southridge. I pitched it to Midwest Gaming Classic on their Facebook page but was told it wouldn't ever be feasible. I don't think anyone ever checked it out really. The current owners have tried renting out portions of it without much interest. There's really no rules in place for anyone that wants to rent it out. As long as they don't totally demolish the place, anything goes really. That's probably why it's appealing to a youtube celebrity.
A company bought it out and never used it for anything. They had this grand idea to turn it into a international Asian marketplace. It was exciting because we don't really have any Asian markets here like Chicago does, except for Phongsaven which is tiny by comparison. Then it flopped. The mayor recently pitched it as a potential site for a new Amazon headquarters/distribution center when they expand. It won't happen though.
