Knucklehead Challenge # 9
At a first glance, this may not look as intimidating as some of the other challenges on this list, but don’t let it fool you. The Knucklehead challenge is more than five pounds of pure America. Hot dogs, chilli, cheese and fries. The big catch with this challenge is that it must be done in 20 minutes or less. Anyone who finds themselves feeling particularly hungry in Roseville California should give this a try.
