I just stuck 15 Flip Flop Flyers hats in my bag at the last minute heading up to AK. I will be giving these away at the show to folks who who "have" (as opposed to those who "will") and don't mind sharing. I suspect they will go quickly...
Remember, the purpose of these hats is NOT to promote the kind of flying that earns them, but instead to identify you as a person with a story to tell to those who might be spared the inconvenience, pain, and embarrassment by hearing it from someone who has already been there.
Also, you don't technically have to have flipped. It was really coined off of the "Ya'll Be Careful Out There" thread that Flip Flop posted to for so many years with fresh cub NTSB reports.
It's a reminder to have fun, but fly safe. Learn from others, and please share what you have learned!
