John and I are working visitor services at North Cascades National Park. We are on reduced staff due to housing - no bunkhouse type lodging allowed, no shared kitchen/baths. This limits the number they can bring in. Offices are closed when they can't close off people. No safe distancing or suitable air exchanges=Office closed. We have about a dozen people on staff (Visitor Center, Interpretive Rangers and Campground Staff). We had a scare early in the season where one staff member had some Covid-19 symptoms. They shut us down for two days while they sanitized the whole building and waited for test results. All clear and back to work. We all wear masks and distance. We sanitize inside the visitor center every day - throughout building each A.M. plus all touch surfaces every two hours. All phones and workstations are sanitized after each use. No visitors are allowed in the building. We use hand sanitizer at our stations and wash hands regularly. Even with all that, I suspect they'd have to quarantine the team for two weeks if anyone tested positive which means visitor services would have to shut down until we got the all clear.
And yes, our campgrounds are PACKED! There have been fights over the first come first served sites, which are also packed. People just set up on someone else's reserved sites and the rangers have to evict them when the people that reserved it arrive. It's a zoo.
Other than campsite wars, almost everyone had been really thankful that we are out there for them and have been considerate when approaching us. Yes, we are standing outside in 90° heat smiling and serving our visitors. (North Cascades is NOT usually this hot for this long this early in the year. We're just lucky).
Some of our hiking trails are also packed. Most people distance and mask when passing, some do not. I try to send people to less crowded trails but some don't care. Many visitors are just here for the drive and overlooks and to GET OUTSIDE!
It's definitely an interesting season.
SO, back to the original post. I suspect Phoenix is in the same boat. If someone has the symptoms, they may have to wait for test results before resuming business as usual.
