I believe Gary said it best, and I agree with him. I've owned my plane for over 5 years. If I really added up all the costs of ownership, It wouldn't make sense to keep it. Flying for even a half hour after work clears my head, demands my full attention and makes me smile like an idiot when I'm done. how can you put a price on that?
I'll keep it til I can't fly any longer and enjoy every minute until I sell her.
