A teen camper in Joshua Tree National Park mistakenly ate nuts yesterday and needed help from the Joshua Tree fire station paramedics. According to Fire Captain Mark Murphy, about 1 p.m., a teen, who was with a group camping at Sheep Pass campground, ate some nuts and suffered an allergic reaction. Paramedics went to the site and gave the teen some Benadryl, and then transported the camper to Hi-Desert Medical Center for treatment.
