Where in Naperville? It's a huge city now, over 140,000 people (it was only about 30k in the early 70s, and then they went on an annexation frenzy and gobbled up everything.)
If you are on the north edge of Naperville and want something a little more "old-school" suburban and less tract-y, you could live in Hinsdale or Elmhurst (depending on your housing budget) and commute on a combination of I-88 and IL-83.
The general consensus is that the best high school districts in the area are (alphabetically):
- Downers Grove (either North or South)
- Hinsdale Central
- Naperville (either North or Central)
- Necqua (sp?) Valley
