If you love semi-trucks the way I do this is a museum for you. Unfortunately they are closed for until April 1st.
It is located out side of Salem, Oregon in the town of Brooks, Oregon. The address is on the brochure, which I hope that if you are interested you down load it and become a member of the organization.
I really enjoyed this museum as it really shows you the evolution of trucks and trucking. They have a lot of different trucks and not all of them are semis there are also a host of other commercial trucks there even an old hearse.
Kind of like the movie "field of dreams," where the question is asked,"is this heaven?" Well, if you love trucks this is your version of heaven.
