I'm assuming that you are referring to Overland Park as well. It's kind of in the "heart" of a lot of other suburban towns in Johnson County. You've had some good suggestions so far, but I thought I would put in my two cents worth. I live in Western Shawnee, which is in the DeSoto School district. It is a great district that is growing VERY fast. If you are looking for neighborhoods with lots of kids, this is the area. Just on our street alone there are about 50 kids, the youngest about 6 months old to about 6th grade. There are a handful of older kids too. Right now would be a buyers market in this area. Unfortunately, there are several houses that have been forclosed on in the area and there are some that have been on the market for SEVERAL months.
We are very close to several highways that can get us all around Kansas city area pretty quickly. But, we still have that "small town" feel where we are at. We have a Taget, Wal-mart and other stores, as well as Hardware stores just a few miles from us too. We are also very close (about 10 minutes) to The Legends...which has a lot of shopping,Nebraska Furniture Mart,restaurants, hotels,a ballpark and the Kansas Speedway.
I grew up in Olathe and would also suggest their schools as well. They are also a growing distric and the housing cost is generally a little less there too. Again, with the markets lately though, I think you could find "bargains" in several areas of Johnson County.
Good luck on doing your research and finding a new home!
