What are the "MUST DO" car events?

[RPOLS3]

I like the idea of adding races to the list of shows as many are a must do if you're a car guy. Haven't been to Daytona for the 500 in 10 years, or Indy for 25 years but those 2 should probably be on the list in addition to an NHRA and World of Outlaws event (can you still walk through the pits with a regular admission ticket?). MCACN, Scottsdale auctions, Mecum events (Indy and Kissimmee), SCR, Bloomington, and some of the larger swap meets like Pomona, Jefferson and Carlisle should also be on the list. My parents have been hitting some of the smaller local rural shows and cruises and I've joined them on occasion - in addition to the great people you meet, you'd be surprised what shows up for cars.
