I received a letter this week asking those who plan on attending the Triple Tree fly-in to pre-register. This will expedite the registration process. You do not need to pay or formally commit to attending. The organizers just want you in the system to speed up the sign in process.
Last year, they had over 800 aircraft fly in & are expecting more this year.
I attended last year & 3 years ago. I could not believe the growth they had experienced.
This is a fun & non-commercial event. Just airplanes & friends.
You can pre-register at
Then select the "Pilot Registration".
I had to make several attempts at entering the authorization code as the validation character codes are not clearly distinct.
Note: I am just another attendee & not associated to the event. I just wanted to pass on valuable info to others who are considering on attending the event.
