The Denver Post reports public health officials are still finding infected fleas in fields surrounding Dick’s Sporting Goods Park in Commerce City. The stadium’s owner decided to ban camping during the concerts over Labor Day weekend, and the band posted the notice on its website Tuesday.

Between 2,000 and 3,000 people were expected to camp.

The band’s well-known Shakedown Street, where fans sell souvenirs and food, also will not be allowed because the area normally used by vendors outside the stadium is on a dirt road.
