Cobra dogs, how did it go from a hotdog shack to a board of an olympian

I have a mild obsession with cobra dogs, I had one last summer, and have been dying to go again.

But it how has cobra dogs grown from a hotdog shack at mt hood, to a massive fanbase?

I have seen 7 people wearing cobra dog hoodies, even I own one.

For gods sake, a few fans made cobra dogs korea, they aren't even affiliated with the one on the states.
