one of the most impressive things I'd seen in the past at SEMA was that some guys had autographs on their SEMA pass... and I realized this year, that I'd take the opportunity too!

 Yup, Don Garlits was at the Chevado booth! And so was Kenny Youngblood! 

Yes, there are other legends and icons there at SEMA, such as Richard Petty, Mario Andretti, Jay Leno, Larry Chen, Chip Foose, Ron Capps, Jimmy Shine, Tony Stewart, Bob Larivee  etc https://www.semashow.com/celebrity-appearances  but I'm not going to spend all my time at SEMA standing in lines for autographs.

 The lines for Richard Petty and Mario Andretti were AROUND the booths. You'd be in line so long that the autograph session would be over by the time you got to the front
