I think that is the ATP in Tacoma, a little South of Seattle. I have never been to the ATP there, but I fly into the airport a lot. It is a really nice area with the Olympic Mountains to the West and Cascades to the East. Be ready for wind and rain, however, if you are coming this time of year.
I got my MEI at ATP "seattle". It is at Tacoma Narrows airport (TIW). They have 1 seminole. It was great because I live 5 minutes away. Good instructors and a great area to fly in.
