A Quick Question About the Vegas Race

Food for thought:

I'm on the bubble about this one though I'm leaning towards the drivers being responsible since they are the consummate professionals, but who's to blame for all the speeding penalties at Vegas last week?

1. NASCAR for limiting track practice, aside from the race weekend?
2. Vegas for moving that cursed limit line?
3. Or the drivers? Shouldn't they have made the appropriate mental adjustments and played it according the the changing playing field? IE: moving line?

There were an awful lot of foul ups last weekend and I sure was surprised, with Jeff Gordon paying a pretty hefty price for his snafu.

As far as track practice goes, wow, I think it's affecting Jr., but then again, it could be something else.

Any thoughts on any of these issues? Anyone? Someone?
