On October 12th & 13th, the Heavener Runestone State Park is hosting its fall Viking/Celtic Festival. It is well worth the scenic trip. You can see several actual Viking runestones (one is the size of a wall in your house), hear great Celtic music and buy all kinds of cool items. It is a very wooded area so it's a great way to escape the rat race.
