on the West Coast:
Rancho Santa Fe in San Diego
South Coast Orange County (San Clemente, Dana Point, Laguna Beach, Newport Beach)
Malibu, Thousand Oaks, Beverly Hills
Monterey County
Atherton, Palo Alto, Los Gatos (Silicon Valley)
Roseville and other NE Sacramento burbs
Medina and Bellevue outside Seattle
Hawai'i Kai, Kahala, and Aina Haina in Honolulu
... lots of wealthy, clean, and fancy looking places near our coasts!
Also Scottsdale and Paradise Valley if you want a desert vibe. And any mountain resort town.
Roseville has plenty of wealthy people, but on a list that includes Malibu, Atherton, and Beverly Hills it might as well be Compton. And if kwabbit thinks Winnetka and Scarsdale don't look rich enough, he'll be
utterly unimpressed by Roseville, lol.
For Sacramento suburbs, I think the only thing that might work would be Granite Bay and certain neighborhoods in El Dorado Hills and Folsom. The trouble is, based on the few Google Streetviews I just looked up, none of the places kwabbit mentioned look underwhelming to me. If those are "standard UMC houses", then what
should a rich neighborhood look like? Just mansion after mansion after mansion?
