A 17-year-old Hermantown teen says he is "still determined" to sleep outside for a year despite temperatures in Duluth over the weekend dropping as low as 30 degrees below zero, the Duluth News Tribune reports.
Rudy Hummel started his personal quest to sleep outside for a year on June 7. Sunday night marked the 211th night in a row that he's slept outdoors in his family's yard.
During the wintertime, Hummel is sleeping in his quinzhee, also known as a snow house. A bale of hay blocks the doorway to keep the cold air out.
The Associated Press said Hummel learned to build the snow house as a Boy Scout in Duluth.
In a blog post Sunday, the teen said he "re-did" his "room," because the "snowy ceiling was starting to slump, making maneuvering difficult."
He also acknowledged that Sunday night he would be "truly tested."
"I have a few tricks up my sleeve, like sticking a hot water bottle in my sleeping bag and lighting a candle inside the cave," Hummel wrote. "Hopefully those will work."
Hummel has been sleeping on two foam pads, 3 inches of straw, a Therma-Rest foam pad, another foam pad and an empty sleeping bag on a snow shelf, according to the News Tribune.
Normally, the teen sleeps in three pairs of pants and four shirts, but for the weekend, he added a hooded fleece top.
Hummel has also added another wool blanket atop his sleeping bags. Before that, he slept in four sleeping bags with three blankets on top.
The story of the teen's quest has not only been picked up by media outlets in the Twin Cities, but by newspapers as far away as the U.K., Hummel's mother, Gail Johnejack, told the News Tribune.
