Of course you can't keep a good racer down, so Mark has come up with a new division which he is starting - Mule Racing.  Check out the photo below of Mark and his new pride and joy.  Apparently he has been screaming around camp Victory with this thing and it's "modified" exhaust.  I guess he didn't read the rulebook where mufflers are required this year.  ;-) 

Thanks for your service Mark and hurry home!
