In addition to looking at Canada, there are several places in the US that are within an easy 1½ day drive from Chicago, allowing plenty of on-site time even within a 10 day time frame. In addition to the one's Michael has listed, consider the Ozarks and Red River area of OK/MO/AR; the central Appalachians and historic areas around Chesapeake Bay; the northern Appalachians including the Poconos, Catskills and Adirondacks; Not much farther - still easily within a 2 day drive - are New England or the Outer Banks
