You can now follow the bears in California’s Yosemite National Park online. No, that does not mean the bears now all have Twitter profiles. But they are connected to the internet via satellite. They have their own website. It is keepbearswild.org. The park has about 500 bears within its borders, and last year, had over 5 million visitors. Now, about 20 bears are wearing collars with GPS trackers. You can follow their movements on a map of the park.
