South Temecula near Hwy 79 has many nice features — I lived there in 2003-4, but many problems too. The traffic at the 79 ramp is tremendous now and you have to ask yourself whether the Pechanga Casino is a plus or not. The drunk driving inspections conducted along Pechanga Parkway on weekend nights slowed traffic quite a bit and made me wonder about the condition of the drivers.
The new Wolf Creek development has some nice homes, but the buyers have paid a premium price, so I would look for repos and sliding values there too.
My idea of a good place to live would be Santa Monica circa the early 1960s. Is there really anyplace in Southern California where the traffic is light, the air clean and the neighbors wholesome? I wouldn’t nominate Malibu (sorry Mel Gibson!)
