The "mission" is ever changing and takes at least two planes to satisfy. 43 years so far, and my mission is still changing. Most of that time I have kept a stable of two planes for different missions. So far, 9 were taildraggers and 1 with a training wheel. Only 1 so far was metal, 1 composite, and 8 fabric. 5 were classic/antiques, and four were E-AB, and one "Modern Era" aircraft. For today, it's a SuperCub Clone for passengers and local fun and a stretch KR-2 to go long distances in a short time. Sometimes I change my mind and end up buying another of the same plane that I had previously owned. The problem now is that I built both of the planes I currently own, and don't think I can let go of them to buy or build another, so the stable may have to grow to three. Not quite sure my long suffering ever tolerant bride will put up with me owning 3 planes again. Life may get really interesting if she finds me out in the hangar building another plane.
