Ari Ofsevit is a guy from Boston fueled by an intense, nerdy love for sports. The day after running this year’s Boston Marathon, his face was all over the cover of the Boston Globe and on all of the network news channels, but on the internet, people were accusing him of cheating. This is Ari’s story.

Part 1: Champagne on the Rocks

This past summer, Scott Jurek set a new record for running the 2,181 miles of the Appalachian Trail. But on his triumphant day atop the last mountain in Northern Maine, his 21st century campaign for the trail's record ran afoul of a park founded on ideas about wilderness from a decidedly earlier time.

Part 2: 10x10

Outside/In kicks off a regular segment called 10x10, where Sam journeys to a 10x10 plot and uncovers the secrets you'd never know to find. Today: the complex eco-systems of vernal pools.

Part 3: The Invasion of the Kiwi Berry

Iago Hale has a vision: it’s one where the economy of the North Country is revitalized by local farmers selling delicious, cold hardy kiwi berries to the masses. Meanwhile, Tom Lautzenheiser has been battling a hardy kiwi infestation in Massachusetts for years, and is afraid that this fight will soon be coming to the rest of New England.

Should we worry about the cold hardy kiwi and what does the quest to bring it to market tell us about what an invasive species is?

Eat The Invaders

The Outside/In team takes a bite out of invasive species.

Part 1: The Wild Boar of Corbin's Park

Outside/In goes hunting. Not for animals, but for the secret of what's behind a 26-mile fence cutting through the woods of New Hampshire, and why some people want it to remaina  secret.

Part 2: The Moose Whisperer

Every year, about 2,7000 of the roughly 50,000 people who apply, receive a moose permit in Maine. If you're one of the lucky ones who has waited 20 years for this moment, you're going to want an expert on your team. You're going to want a moose whisperer.

Part 3: Cute Predators

Whn you think of predators, you probably think of lions, tigers, and bears (oh my!), but some predators are adorable little fluffs of feathers.

Part 1: Fortify. Accommodate. Relocate.

Nahant, Massachusetts is a rocky crescent moon of land out in the Atlantic Ocean just north of Boston. It has a long history of being at the mercy of the ocean, and the people who live there are looking at an uncertain future. The seas are rising, and no one can say how long many homes by the water will be safe.

Part 2: The (Second) Greatest Show on Earth

Mount Washingon is famously home of "The World's Worst Weather", but it also hosts a massive amount of tourist infrastructure. Outside/In tells the tale of how the mountain was conquered, and how that process became the template for mountain tourism nation-wide.

Part 3: Next stop...the moon!

Is there anyplace left on earth, or beyond, where you can plant a flag and take a claim?

Part 1: Never Bring a Sledgehammer to a Scalpel Fight
Is biocontrol the best option for combatting invasive species, or the height of human narcissism?

Part 2: Eat The Invaders
The Outside/In crew does its parts to beat back invasive species, by eating them.

Part 3: Look Toward The Dawn
Step back and imagine a world before GPS, before compasses, before maps. While it might sound scary, you could also discover a sixth sense...one that's been inside you all along, waiting to be turned on. 

For alpinist Ben Clark, scaling the world’s toughest mountains is a source of pride and peace; for his mom and dad it is a source of constant worry. What's a parent to do if their son’s lifelong ambition puts him in harm’s way? Plus, The “Save the Whales” movement of the 1970’s was instrumental in putting a stop to commercial whaling. But even as humpbacks and other whale populations have bounced back, one species is still up against the ropes. Literally. Later in the show, Sam tackles the problem of whale entanglement and discovers that proposed solutions include crossbows, Australian lobsters, and Chinese finger traps.

If you’re even the least bit interested in solar power, you’ve probably come across an obscure, hard-to-parse, seemingly conflict-free term: net metering. It’s a system that has come to be the bedrock of the American rooftop solar industry, and the root of one of today’s biggest energy battles. It was also started by a dude named Steven Strong, kind of by accident. Buckle up folks, we're going full energy nerd.
