Guess time may tell.
Sitting out a year for a Hendrick seat to open up? Going to IndyCar? Sports Cars? Only Carl knows.
Well whatever the reason is I just can't see someone in that position waking up one day and saying, Hey I think this is dangerous, I think I will quit.
My guess is he had some outside influence.
At the least you would expect him to finish the last year of his contract.
But hey, any way it boils down I hope he does not end up regretting his decision and he enjoys life.
Something tells me he would need to get an OK from the wife first.
