When it seems like the rain is never going to stop, don’t despair! Whether your tastes run more towards Portland puppets or Troutdale trains, Multnomah County has no shortage of fascinating and quirky museums that won’t cost you anything. (Check the links for updated hours and contact information.)
Whimsy. Revisit the toys of your (or your grandparents') childhood at Kidd's Toy Museum. And if your pipsqueaks are pleading to ponder a plethora of puppets, perhaps Ping Pong's Pint Size Puppet Museum is your pleasure.
History. We love that the Gresham Historical Society museum is housed in an original Carnegie library! Not to be outdone, the Troutdale Historical Society has three museums: The Barn Exhibit Hall, The Harlow House, and The Rail Depot. And don’t forget, the expansive and amazing Oregon Historical Society is free to all Multnomah County residents; just be sure to bring a proof of residency that includes photo identification.
Miscellany. Check up on medical history with the fascinating exhibits in the Main Library of Oregon Health & Science University or the Dr. Ernest E. Starr Memorial Museum of Dental Anomalies in the OHSU School of Dentistry. If you're interested in "the art and industry of the cast letterform," then the Museum of Metal Typography is definitely your type. Then float on over to the Lincoln Street Kayak and Canoe Museum to learn more about indigenous small watercraft and suck up some cleaning history at the Vacuum Museum at Stark's Vacuums.
