Before the six remaining teams make it to Flagstaff, Ariz., Tyler Florence calls them up to let them know that their first challenge is underway: The team who sells the most in Flagstaff will get a one-hour head start to their next stop, Sedona, Ariz. In Sedona, the teams must make a dish incorporating the local delicacy, rattlesnake/rabbit sausage, and leave the comfort of their trucks to sell from Pink Jeeps.

The five teams arrive in Santa Fe, N.M., where they are faced with hot weather and hot flavors when Tyler challenges them to use peppers to create a dish that's representative of the city. Later, they are given only one hour to shop for an entire weekend of selling.

The final four race to Texas, where steak determines how much seed money each team receives. Later, a Speed Bump is encountered; and an elimination occurs during a visit to the Cadillac Ranch in Amarillo.

When the top three teams arrive in Tulsa, Tyler Florence takes away their phones and internet abilities: All of their research, outreach, marketing and navigation have to be done the old-fashioned way. He then challenges them to build roadside attractions to pull in customers. On their second day, the teams sell at one of the last drive-ins on Route 66. They race from car to car, knowing that each lost sale could be the one that sends them home.

Season 6 comes to a finish with the final two teams arriving in St. Louis, where Tyler challenges them to create three dishes with three different proteins in 30 minutes. Then, it's off to Chicago (well, after a quick detour) as they race to sell three different ethnic dishes in three different neighborhoods in hopes of winning $50,000.
