You can't blame Nascar for the condition of the track, they had nothing to do with it, blame Mother Nature.
Until they get rid of the restrictor plates,its not going to change much, as far as the pack racing goes. A 2 1/2 mi race track is past it's time as far as stockcar racing goes. Speeds have outgrown what the track and cars can handle. In the 50's it was cool to see those big old boats, convertibles too, hitting 140mph. With today's technology I'm sure they could do 130mph without batting an eyelash.
No easy solution, except the Golf Channel, for now.
