“If the price gets up to $3,000, I’ll buy everybody here a beer!” My attempted conversation is drowned out by the sound of 500 people cheering. New Belgium Brewery is auctioning off a signature “Fat Tire” beach cruiser bike. Proceeds from the sale benefit the Des Moines Bike Collective, a Des Moines based nonprofit. The man holding the current bid immediately raises his hand to increase his own bid to $3,000. And the cheers get even louder.
