I was lucky to have a chance to take a walk to Yosemite National Park. It's a nature reserve in California, the state of the United States, about four hours by car from San Francisco. I see that the Yosemite ecosystem is rigorously maintained in such a way that it does not receive too many "foreign goods" into the region. Impact, among others, people can not practically receive a phone signal, let alone the internet, because the telephone signal tower could not be built. Only occasionally, when riding a car on high, my phone can receive a signal.Yosemite is the most famous national park in the United States. He is known for beautiful natural scenery. I only visited the Yosemite Valley, an area of ​​18 km2 or just half a percent of the Yosemite National Park area. This is the most popular place in the region.amazimg @dmytrokprol
