The US Coast Guard closes parts of the Potomac and Anacostia Rivers for an Army celebration

The US Coast Guard will enforce a security zone on parts of the Potomac and Anacostia Rivers in Washington, DC. This means boats cannot enter or stay in these areas without special permission during the Army's 250th Anniversary celebration.

This is a temporary measure, but it shows how easily public waterways can be restricted for security events. It highlights the ongoing tension between public access and security concerns in urban areas, especially around government facilities. These kinds of restrictions, even short-term ones, can disrupt local businesses and recreational activities.
