I just uploaded a KML file of Seaplane destination waypoints that you can load into Foreflight and use for flight planning. It is on the destinations page of the WSPA website available for download.

Instructions from Foreflight on how to load it onto your iPad are included as well.

If you have issues: 1) read the instructions again, 2) contact me at austin.watson@ieee.org
