I've been a casual fan of NASCAR over the past few years (Formula 1 is my favorite) but with two things happening next year I might amp up my interest in NASCAR:

1. Juan Pablo Montoya is leaving McLaren at the end of the year to drive NASCAR
2. Red Bull is sponsoring a team

When it comes to sponsorship, Red Bull usually jumps in with both feet, just look at F1 where they sponsor two teams: Red Bull Racing and Scuderia Toro Rosso. Red Bull is working hard to ramp up their marketing efforts in the US and NASCAR is an obvious target.

As for Juan, he's been stagnant at McLaren, so perhaps the jump to F1 will give him a boost.
