All the states have aeronautical offices. Many give away free state aeonautical charts, airport data books and etc. Click:http://www.dot.wisconsin.gov/travel/air/state-sites.htm

Interesting, but I can't find a single chart. Can you point me to at least one.Nejc

At each state..and some do not offer them..look around for "publications" etc. When you find them, they will ask for your address to mail them to you..they are not (usually) instant, although some are in PDF format. Chats are also available (though just window-sized sections) at: http://www.earthmaps.com/mapserver.htm
