Stop extortionate corporate trademarking of natural wonders and historical buildings in our National Parks.

The soon-to-be-former Yosemite concessionaire, DNC Parks & Resorts at Yosemite, Inc. (DNCY), a subsidiary of the Delaware North Companies, has trademarked many names around Yosemite, including "Yosemite National Park," as well as the classic sketch of Half Dome. They are currently trying to extract $50 million from the National Park Service and/or Aramark, who won the new concession, for these "valuable trademarks." This should not be possible.
