I have never been a fan of Temecula/Murrieta. To me it is another poster child for sterile, generic, cookie cutter, over master planned suburbia. The same chain restaurants, the same chain stores, the same car culture, boring uninteresting generic people, the same tract homes as anywhere generic suburban America. The only part I like of that whole region is the small street of old Town Temecula. Wine County is OK too. If you dropped someone blindfolded in Temecula/Murrieta and took off the blindflold, they wouldn’t know the difference from any other generic suburb like Phoenix or Dallas or wherever. It’s just so generic and BLAH I could personally never live up there.
To me a lot of inland North County SD is not much better. Places like downtown Encinitas & Cardiff by the Sea around the hwy 1 are cool, but outside of that it’s pretty blah too.
