I just saw this thread today after emailing Mark out of the blue to catch up with him and all I have to say is WOW!
I just chatted with him on the phone and he sounds to be in great spirits and really concentrating on his recovery. He has the right attitude and mind set to heal quickly and correctly which is a huge plus in this situation. He is one of the nicest people I have met in a long time and I am sorry this had to happen to him, and I just wish him a speedy and healthy recovery.
Can't wait to see you back out on the track, Take Care!!!
