The Wood brothers killed their own team. They are located in Stuart Va. with a population of 961 as of 2000 census. Located in a county with just under 20k population. If you had a motorsports background and a degree in engineering, would you move there? Even Petty had to move their shop to get better qualified people to work for them. But it was all a bit too late to have an impact for the Petty team.
Granted all that, i do hate to see them struggling as I live within 30 minutes drive of their shop. But many teams have come and gone in this sport. Jr. Johnson, Holloman & Moody for example. Many more teams will come and go in the future.
