I'm so very happy to have my plane that every year or so I email Joe, the previous owner, and thank him for selling his plane to me. I include some pictures, like me flying with my grandkids.
He realized he had made a mistake (for him) selling his Bonanza and trying to step down to the 150; so, he wasn't really attached to the 150. Still, I think he enjoys hearing from me and knowing how very much I appreciate my plane. He went from the 150 to a Citabria and then to a J-3 Cub. It's about time to email him with my thanks again, and it'll be interesting to see what plane he has now.
