According to this post on Facebook, employees at QBP “spent weeks turning this year’s copious snow into a fat bike demo course” for their annual Frostbike dealer show at their headquarters in Bloomington. (I was there yesterday, doing board member booth duty at the MORC booth.)
I don’t know for certain, but I’d bet that John Gaddo was the instigator, designer, and chief test rider. (I stole the above left photo from his Facebook profile.)
