    My previous statement on this subject was meant to say the wheel parted from the car when the studs pulled out. Apparently when I edited it I failed to update my edit. I apologize for any...

    Scott,

    I like this idea because of the opportunity to run in a national class relatively cheaply. My own circumstances would probably preclude doing so right away--just got married at 60, a five...
