NASCAR: Rule changes to be clarified

The 29th annual NASCAR Sprint Cup Series Media Tour opens on Monday in the Charlotte, N.C., area. It's a four-day smorgasbord of announcements, team-shop tours, optimistic predictions and the unveiling of new race-car paint schemes, team members and sponsorships. More than 150 writers, broadcasters and photographers will get a steady diet of claims such as “we're excited,” “we've been working harder than ever,” “we feel we've got everything in place” and “we can't wait to get started.” The tour will visit almost every team that plans to run the full series schedule in 2011, teams such as Earnhardt-Ganassi, Stewart-Haas, Penske, Michael Waltrip, Richard Childress, Kevin Buckler's TRG, Team Red Bull, Furniture Row, Richard Petty, Hendrick, Roush-Fenway and Joe Gibbs.
