My wife and I were in Colorado for a week visiting our Denver daughter. We returned early this morning. We stayed in Crested Butte over the weekend. A haze was high in the sky from fires, but there were no ‘close your windows’ alerts. One major fire is in Ouary. We stayed there last summer. There was at least a partial evacuation of the town. The air is so dry out there. I noticed 9% humidity on a weather report.
