Have two houses in Kansas that were both tested and required systems installed at the sellers expanse. Coming from California, I had never heard of Radon, except bad memories of chemistry classes. As I recall, the systems were not that costly.
In high school my daughter played polo. In addition to our two horses, we would occasionally need to rent horses for a tournament. $150 to $250 per chukker, 7.5 minutes. when she went off to college we sold the horses and I could suddenly afford to start flying again regularly.
1 - Survive my first annual. Just spoke with my mechanic and it may be possible.
2 - Fly more hours then the last 12 years combined. Won't be very hard.
3 - Start my IR.
