NASCAR must do a better job of appealing to new fans to continue its' phenomenal growth.  To GROW, however, they must SHRINK!

SHRINK THE NUMBER OF NETWORKS/COMMERCIALS!
Most fans are introduced to NASCAR primarily through TV coverage.    Having ESPN/ ABC, SPEED, TNT and FOX has created a jumble of TV commentators who don't know the sport and provide no consistency in race coverage.   Many fans don't have cable and the broadcasts are, at times, painful to watch.  I'm a rabid fan and even I can't sit through a broadcast without my Tivo.  How will a new fan do it?   These broadcasts need to be consistent again with commercials side by side with the racing action.

SHRINK TICKET PRICES!
NASCAR needs to help new fans attend a race in person.   The average family has to drop between $500 and $1000 per weekend to attend.  Now you're competing with a vacation!   In order to increase NASCAR's appeal to minorities, families with kids, and the under 25 crowd, they must cut ticket prices and increase one day tickets vs. weekend packages.

SHRINK RACE LENGTH!
Shorten races from 500 miles to 400 miles.  It won't inhibit the flow, strategy, or competition of the races.  Marquee events like Daytona and Bristol should remain 500 miles. Retain the 600 miles at Lowe's to keep those engine builders on their toes.  More fans will watch all 36 races if they don't take all day.

...but then again what do I know, I'm just a SHRINK!
