Wow, wow and more wow! We took a 3-week round trip from north to south and up the west coast. We visited as many national parks as possible, with all the corresponding types of weather. For instance, one day you are standing in the hot sun and the next you are ankle-deep in snow in the mountains. We also experienced a tornado alert, but they didn't really look surprised themselves. We have had beautiful weather and in Death Vally even almost a heat record with 54 degrees celcius.— This text is automatically translated to English
