For the past decade, at 8 a.m. on the first Friday in May, Yellowstone National Park ranger Dennis Lenzendorf has pulled aside a locked barricade to open the park’s East Entrance to the season’s first visitors. But this year was a little different.
Normally, a few dozen cars—mainly full of locals anxious to re-enter the park on opening day—are queued up and waiting. But typically, after the first hour, traffic is sparse. This past Friday, more than 50 vehicles were still lined up at 10 a.m. waiting to enter.
