Event Coverage Milestone Events

The thread for the 50th NSRA Nationals is getting quite a bit of attention. I thought about other milestone events I have attended. I am fortunate to have the time to have made this possible. Also, I have been able to click a number of events off my bucket list this way. These are the ones I can remember.
50th Bonneville Nationals - 1998
50th Grand National Roadster Show - 1999
25th MSRA Back to the Fifties - 1998
25th Frog Follies - 1999
50th Detroit Autorama - 2002
50th NHRA U.S. Nationals - 2004
50th March Meet - 2008
50th Knoxville Nationals - 2010
50th L.A. Roadster Show - 2014
70th GNRS - coming 2019
50th NSRA Nationals - coming 2019

Many of these events I have been to only the one time. I hope I have the years right for all these.
