(Portland, OR)  --  More than a dozen museums and attractions in Oregon are coming together to issue a joint statement about wearing masks.  They're requiring all visitors to wear masks, especially because children younger than 12 can't be vaccinated and it will help protect their health.  The attractions include the Oregon Zoo, Portland Art Museum, Oregon Coast Aquarium, Oregon Historical Society and the Oregon Museum of Science and Industry.  They say that as conditions change their policies may change.
