The March Meet is a spectacle well worth seeing, although the weather in recent years has been sketchy at best. We've sat out the last three years with the feeling the costs (as a competitor) out weights the benefits.
The CHRR since NHRA proper is a shell of what it once was. When it was ran by Steve Gibbs and the museum it too was a spectacle worth seeing too. Anymore IMHO, it's just another NHRA event with a rigid format catered to the nitro cars and doesn't have that magical buzz to it anymore.
Since retiring, Steve Gibbs has put together a couple of Nitro Revivals and has shown good success, though there is no racing. It is a good time to meet and greet some of the legends and see some of the cars from the past. There is a possibility there will be another one later this year here in So. Cal, but nothing is official yet.
