That's one beautiful machine, congrats!
It is a very inexact science to know when that "day" is. I thought mine had come when I had my bad accident back in 2009 (car turned left in front of me).
We'd like to think we can control everything, but that is a fallacy. As many of our accidents prove.
But after 7 years out of the saddle I was back in. In the meantime I share your 4 wheel addiction but I really missed riding. I've tried to moderate my riding and certainly the residuals of that broken back brings some pain along with riding. But I guess it's better to be able to participate rather than not experience the joy of riding even if I ride Very conservatively now.
There is no Day really; you just hope to participate a's long as possible to enjoy that and the friends we all have made. Much more brotherhood here than in most of the car scene.
But seriously - enjoy that car AND your motorcycling. Here's to hoping the enjoyment goes on for a LOONG time!
