For one evening each year the Washington Seaplane Pilots Association (WSPA) has the pleasure of welcoming you and your guests to an evening of fun at the Museum of Flight. Our Annual Grounded Hogs Gala Dinner serves as our primary fundraiser to help fulfill the organization's mission to protect and grow seaplane access to Washington waters, promote safe and responsible seaplane operations, foster communications among owners, operators, service providers, and the community, and to facilitate events sharing the joy of seaplane flying in Washington and the Pacific Northwest.
