Found this wonderful web site when I was looking for maps to track our post cards on. www.clickandlearn.com/documents2/BlankMaps.htm
Try this one: http://www.worksheetworks.com/geography.html Find a map of the area you're looking for, remove all the stuff that you don't want and then download and print it out. You can leave in some things like rivers and mountains without any labels. It prints much nicer than the bitmapped graphics.
