The good things are that it’s safe, quiet, and if you’re in a poor situation as a young adult, Wheaton has a VERY good youth outreach program (see http://www.outreachcommunityministries.com/ —they’re a christian organization, but they don’t preach at you if you’re not interested and they’re very nice).
The bad things are that it’s a very religous town with churches everywhere you look, very republican, very traditional, and very boring. Aside from Cosley Animal Farm (which someone posted pics of) and the Prarie Path (which is excellant to bike on), there’s not much to do…you always go somewhere else to do things.
The most interesting thing is, despite being very religious and republican, it has the headquarters of the Theosophical Society of America ( http://www.theosophical.org/ ) which is this weird occult/alternate religion place. Why they’re in the middle of a mostly christian town, who knows, but they have an interesting metaphysical bookstore for the New Age types and those studying religion as their majors at Wheaton College.
