The very active antiquer and biplane community at Felts Field, Spokane, WA held the Northwest Biplane Fly-In last weekend. 72 aircraft showed up and that included a beautiful F-2 Waco and 5 Staggerwings. Addison Pemberton gave 30 Boeing rides and there was a lot of formation work.
Skeeter Carlson brought out his Tommy Morse Scout with a LeRhone and we ran it every hour all weekend - here's a video.
There was also a 10 ship biplane formation - also with video:
