Thought of as the OC of the midwest - which is somewhat true
While theres plenty of money floating around here its not quite as rich as its made out to be though.
Mission Hills, Berry Hills, and parts of Leawood are the main rich areas.
big fancy cookie cutter houses are common in the northern parts but the larger, more unique mansions can be found spread out around Stilwell (where i live) (10-15 minutes from Mission Hills, 5-10 minutes from Berry Hills)
To see the those examples ask anyone from stilwell to show the Miller's house (big brick house on Metcalf Avenue (cant miss it))and the nearby neighborhood or ask them to take you down Mission Road (long curvy road that branches off into a ton of long dark gated drives in Mission Hills (often a big hangout for santanists - its not a huge problem anymore, but its still a problem))
Most kids in Johnson County are in the Blue Valley school district and most of the Mission Hills/Berry Hills, and Leawood teens go to Blue Valley High School (where i go)
which is a pretty good representation of JC's social status-
Abercrombie/ Hollister/ Guess/ect clothing
15-20 Coach bags in every hallway
plenty of brand new mustangs/ f-150's/ scions/ect in the parking lot
(along with one black Hummer H2 with 26" wheels)
and plenty of Audi's/ BMW's/ Acura's/ Denali's/ Escalade's/ Naviagtor's in the Drop-off/Pick-up lane
"oh... Blue Valley/Johnson County... that explains a lot..."
