Borrego Springs is unique! One reason is probably because of its location - smack in the middle of the largest state park in California. Borrego is a "donut hole" community surrounded by the Anza-Borrego Desert Park for miles in all directions. There is no commercial airport, although you can drive to Borrego Springs in two hours or less from San Diego and in a little more than an hour from Palm Springs.
Borrego is surrounded by the same mountains that make Palm Springs so beautiful, but it is somewhat of an "anti-Palm Springs". Residents (and visitors) don't spend their days shopping high-end boutiques or eating in 5-star restaurants. They take a much simpler approach to "living" - waking early, tending to their gardens, golfing with friends, volunteering at the park and hiking its trails. There is a significant appreciation of nature and focus on the vast desert surrounding the community. Borrego Springs is peaceful.

Although it comes at a price, Borrego has been able to avoid retail sprawl, fast food chains and traffic lights. Residents are proud of that. And Borrego Springs is one of only two designated "dark sky communities" in the country along with Flagstaff Arizona (http://www.darksky.org/).
My nephew, Sammy, and I spent an afternoon hunting down the life size animals/miscellaneous sculptures and taking pictures! Its a day I won't forget and should be on every family's "to do" list if in the area.
