I dug into this because I live in Oregon and was thinking about checking it out for a giggle, but for real, his website: https://airplanehome.com/VisitorsInformation.html#Anchor12

Really does insist that if you show up (even unannounced) to climb up on his airplane and bang on it/yell until he comes out: "Please do wake me boldly sans any regrets."

I might have to head out there as it's basically a suburb of Portland where I live.

He seems like a very kind eccentric.
