Explanation:

City parks are often owned by local - government entities (city governments), county parks by county governments, state parks by state governments, and national parks by the federal government. In a sense, since these governments are meant to serve the citizens, the citizens of the United States can be considered the 'ultimate owners' as the government holds these lands in trust for the public. Private corporations do not own city, county, state, or national parks.

the citizens of the United States
