I found an excellent coloring page site. Blue Bonkers. Excellent = A site where you can print out free authentic-looking Lone Ranger coloring pages. We are still searching for Gene Autry and Roy Rogers.
There are many more themes than the Lone Ranger, though. The ones I have seen are good quality for free printables.
The kids like them because they look like book illustrations. I like them because my kids are not normally "colorers," but they get excited about these. It is like they are imagining a story as they color the picture.
