Laura Pierson opened up to Wonderwall.com in 2016 about what she did after winning "The Amazing Race."

Dr. Brent Ridge (yes, he's a physician too!) and Josh Kilmer-Purcell married in June 2013. Brent accepted an adjunct faculty position at the State University of New York at Cobleskill in 2014 to teach marketing. The prize allowed Josh to move to the farm full-time, so he left his job in New York City. Josh shared a glimpse of farming life with his husband with "Philadelphia Gay News" in January 2015. "We didn't know what to do with all the goat milk we had and we met a woman who was producing this great goat-milk soap. We began working with her and it was our very first product," he said. "Now we work with over 50 different local artisans." Today, their farm has grown into a lifestyle brand, Beekman 1802, which features food, beauty, home decor and apparel.
