For more than 1,000 nights, a Duluth Boy Scout named Isaac Ortman has slept outside.
He built and slept in a snow shelter called a quinzee. He pitched a tent. And for the past two-plus years, he's spent most nights in a hammock strung between two trees in his backyard.
Even as the mercury plunged to double digits below zero. Even when a bear visited. Even when the whipping wind gave him motion sickness as he swung wildly in his hammock. And yes, even with his arm in a cast.
So, why is he doing it?
"It's just fun," he said.
Isaac isn't angling to break any records, raise money for a good cause or go viral on social media. It's just that he likes a challenge. Now a 14-year-old ninth-grader, Isaac was just 11 when he began his outdoor endeavor on April 17, 2020.
During those early pandemic months, most group scouting activities were canceled. His troop, like many across the country, held a "virtual" camping trip, with everyone sleeping outside in different places on the same night. Isaac camped at his family's cabin near Pequaywan Lake about 45 minutes north of Duluth.
And then he just kept going.
