Ronald Reagan when it served in the Philippines.

The museum plans a Lego scavenger hunt, a Lego building zone with thousands of bricks for building, popcorn and a Lego movie, door prizes, a market to purchase used Lego kits and other Lego items, and an opportunity to win a classic bi-plane ride for two in “Sunny,” the big yellow WACO airplane.
