Officials with the Tri-County Health Department and Colorado Department of Health told concert organizers and attendees of the upcoming Phish concert at the Dicks Sporting Goods Park in Commerce City, CO they would be unable to camp over fears of pneumonic plague.

Infected fleas and dead prairie dogs were found around the venue prompting health agencies to take action.

Officials informed organizers that activities could continue on the grass fields and paved lots, as well as in the concert venue itself, but not on any dirt fields, including the dirt parking lots, said Don Strasburg, co-president and senior talent buyer at Denver-based AEG Presents Rocky Mountains.

Monte Deatrich Tri-County Health Department envrionmental health manager said “They should be safe walking in and out of the venue… They should stay out of the areas that are posted. As long as they stay on asphalt and go to the concert, they should have a good time and be safe.”
