The Boy Scouts have a new site for celebrating Scouting and a lot more physical challenges to endure at this year’s National Scout Jamboree, NBC News reported. Scouts had to undergo fitness exams and obesity screenings for this year’s event, which starts on Tuesday. There will be no bus circuits or personal vehicles on site and participants will be hiking even more than in the past, according to the Boy Scouts of America website. The Boy Scouts used the CDC’s body mass index as a screening tool this year and those with a 30.0 or higher BMI were prohibited from participating. More than 30,000 youth and leaders are expected to participate in the 10-day jamboree at the Summit Bechtel Family National Scout Reserve in West Virginia.
