Its nice but not too developed.
We're in whats called the Morongo Basin, which includes 3 towns.
From west to east there is Yucca Valley (Pop 20,000), Joshua Tree (Pop 10,000), and 29 Palms (Pop 20,000 plus another 15,000 on the Marine corps Base).
I like it because I can be in L.A., San Diego, Phoenix, or Las Vegas in three hours. And its very peaceful and serene here.
We have a lot of Tourists come out here to visit Joshua Tree National Park.
