I came across Wil's blog years ago, while researching primate penises, and have been a fan of his insightful, comic take on life ever since. What more do you need to know?

Tony was our door into Terlingua, Texas. Thanks to his quick response to an Instagram, we met all the good folks of that town, and ended up staying way longer than we'd planned. If you get out that way, drop in at his bar: TABC (Terlingua Adventure Beer Company), and give him a big hug from us.

Cyrus believes in creating films which promote curiosity and ecological literacy. He's been directing documentary films for fifteen years since his award-winning surf film Riding Waves in 2003. He won a Southwest regional EMMY when he was 23 and has directed hundreds of short films since.

These dudes are smart, funny, and talented. I caught up with them on tour, after their show in San Diego. If you like to have fun, catch them if they come to a town near you!

Lisa Menna uses the wonder provoked by her magic tricks to trigger real magic: the kinds of thoughts that can make the world a better place. Having performed in over 40 countries, Lisa and her organization (Cause to Wonder) are working to show people around the world that good things come to those who respect and protect women and girls.

I caught up with Oscar-nominated director Josh Fox in New Orleans (Gasland, How to Let Go of the World and Love All The Things Climate Can't Change), where he's doing his Josh Fox things: writing, organizing political protests against a fracked gas power plant, playing music, creating art (paintings), and eating a lot of crawfish. His cat Sandy joins us to rub her face on the microphones.

Diana is the founder of a boutique LGBTQ family law and mediation firm based in New York City and Frankfurt, Germany, serving primarily same-sex couples and non-nuclear families. Diana is about supporting  healthy, stable families, whether between same-sex couples, platonic co-parents, polyamorous families, or different-sex couples, by facilitating conversations that support the creation of clear personal agreements, as well as solid legal agreements to protect their families.

Like millions of people, I first became aware of Jeff Leach when I read about his attempt to transfer a hunter/gatherer's fecal matter to his own colon as a way to study the human microbiome. Little did I know I'd find myself sitting at the table with him in rural Texas a few years later or that he'd agree to share his insights with me on a podcast. Jeff's published in Science, Nature and everywhere else a groundbreaking researcher could dream of, but he's too busy with new projects to reflect much on past success.

Cassie and I met John Duarte at a highway rest stop in Dateland, AZ. He was riding his bike from El Paso to San Diego, which is a short "training run" for him. Join us for this spontaneous conversation in the van. #vanthropology2018

Mike has been my best-buddy since I was 15 years old. The Mr. Spock to my Captain Kirk, he's kept me marginally out of trouble for 40 years now. Mike's a talented musician, speaks several languages fluently, and comes out of a confluence of culture and history. There's nobody quite like him.
