Due to unfavorable weather, the Keystone Safari in Grove City has postponed its popular helicopter Easter egg drop from March 31 and April 1 to April 6 and 7.

During the event, thousands of Easter eggs are dropped from a helicopter at various times of the day. The event is free and open to the public, and park admission is not necessary to attend.

Despite the postponement, the park did open for the season on Saturday, March 30.

“The safety of the pilot, guests and animals are our top priority,” reads a message on Keystone Safari’s website.
