Good. ****** off!!!

That's a shame Paul, but you have totally understandable reasons to stop (not that you need to justify it to anyone). Life is very short, and at least you've had a go. It's an experience that millions of bikers will never have.

I think you've been an inspiration to a lot of people for having the balls to get out there in the first place, and even after eating tarmac twice you still came back for more!!
Just be careful around Mav's ring
Take it easy fella
