The skies over a scattering of Western U.S. cities will stay dark for the third consecutive Fourth of July as some major fireworks displays are canceled again this year, this time for fire concerns amid dry weather, along with pandemic related supply or staffing problems. The city of Phoenix said it canceled its three major Independence Day displays because it couldn't obtain the necessary fireworks due to supply chain problems. Displays in several other Phoenix metro cities are still on. Flagstaff in northern Arizona will carry out its annual Independence Day parade through the city's historic downtown, but a new laser light show will replace the standard pyrotechnic display because of concerns about sparking wildfires.
