When I lived in N.E, Ohio, I would build more in the winter than in the summer, but I flew & built all year round. Now I live in N.Carolina & fly more in the spring & fall, (due to heat) but still build all year long. I am probably 50/50 in loving the building just as much as the flying. In all 32 years, I have never done an A.R.F & have really only considered it only once. Kits, or scratch building has been the only way. There have been a few swap-shop type buys through out the years, but those are not true arfs in my book.
