I have never been to the Joshua Tree National Park in California. I guess it is full with Joshua Trees. Just like this one. To see one, you don’t have to be in California, you can see plenty of them in Arizona on your drive from Las Vegas to Flagstaff. To get better views and get close to them it might help if you get of HW93 and I40. Take some of the side roads. Who knows, you might see something totally unexpected.
