We moved to Naperville in Oct. & love it. We live on the SE side, 10 min. from I355, 15 min. to the Morton Arboretum. I highly recommend the district 203 area of Naperville (eastern side). Rt. 59 (10 min. west of us, in district 204 & bordering Aurora) is very congested. D204 schools are also very congested. We specifically wanted D203 for my son (only 2 now) b/c test scores are a few points higher than D204, and are enjoying a more mature neighborhood (15 yrs. old) w/ beautiful trees & great neighbors. Our lot is a little over 1/4, so not as big as you want, but we also looked at Lisle (Green Trails), Wheaton, Woodridge & Naperville, and our yard is one of the biggest we saw. In my experience, downtown Naperville is only congested on the weekends & evenings, but even then I've found parking w/out too much trouble. Good luck!
