Aquarium Visitors Pay What They Want For The Day

BALTIMORE (WJZ) -- People line up outside the National Aquarium for a chance to pay whatever price they want for admission.

A lot of visitors took the aquarium up on this rare opportunity Sunday.

Last year, more than 7,500 people appeared for the first "Pay What You Want Day."

It was all part of a chance to give back to the aquarium and support its mission of inspiring conservation of the world's aquatic treasures.
