The Great Oregon Steam Up near Salem, Oregon is a great place to take your family for the day. Besides the totally interesting old steam tractors that are the main focus of the event, there's great food, flea markets and a variety of interesting and very cool exhibits.
You wouldn't think that a festival centered on old steam driven tractors would be much fun or very popular, but you would be wrong on both accounts.
This year's schedule is as follows: July 28-29 and August 4th and 5th. Visit the organizations website for more info.
