Mike and Frank are in Springfield, Massachusetts, the birthplace of Indian Motorcycles. While there, the guys chase a legend that could be a real buried treasure, and drop a massive amount of cash on a stash of classic motorcycles.

Danielle and the guys kick it into overdrive when they land a high-profile custom pick for Dollywood, the theme park owned by legendary country music star Dolly Parton. A tribute to the Smokey Mountain Fire Patrol of the 1930s, the park's brand new roller coaster wouldn't be complete without some key pieces of vintage petroliana. And the team has just two weeks to uncover a long list of hard-to-find items.
