Carlisle or Nats-which is better?

If you're into drag racing, the Nats are better. If you're going to see show cars and parts shopping, Carlisle is better. Both have alot of vendors, but many of the vendors at the Nats, are the same ones that were at Carlisle the previous month selling what they have left. Carlisle is better organized and alot more relaxing atmosphere. Carlisle is probably alot more family friendly as they provide clean restrooms, clean port-a-potties, lots of choices for decent food vendors, and activities for wives and kids. Its been years since I've been to the Nats, but couldn't say it had any of those things.
