    "Great access to highways to downtown, to the airport and for travel. Access to trains to get Downtown but you need to drive to the depot. No real village downtown but access to the best shopping center in the world. High end stores abound. Costco is the largest in the area."

    "This is a well established area with huge trees and large lawns. Most of the residents are families and empty nesters. Friendly residents, many of whom can be seen walking their dogs daily. It is a beautiful, serene, secluded enclave only 5 minutes from the Oakbrook Shopping Center and Fortune 500 company offices. A trip into the city during non-rush hours is about 20 minutes."
