I'm with MinnFlyer; for me, flying is a sport, but the challenge of building is the real hobby. The more of my ideas I put into a model, the greater the satisfaction. Assembling an ARF is OK, building a pre-cut model kit is better, building from plans is better yet, and designing and building a model is best. Flying my newest one-off creation is my greatest satisfaction. Even though I live in So-Cal, flying gets a little boring at times, designing and building is a much welcomed change.
