Too bad this isn't at an airport. But maybe there is hope yet.

Less intrusive security procedures will begin at Independence National Historical Park tomorrow, easing the movement of visitors to Independence Hall and the Liberty Bell, according to park officials.
Screening for Independence Hall will take place between the hall and the first Supreme Court building, commonly known as Old City Hall, directly to the east of Independence Hall.

All magnetometers have been removed from the park.

Visitors with bags and packs will still be subject to visual screening, but X-ray machines will no longer be used.
