Having fun -- Ken, here's a suggestion about having fun: Make an effort to remember your first run on the Salt. Take a look around at the line of race vehicles behind you, pay attention to the starter that'll be giving you a few seconds of calm-down chat and maybe some advice, look down those two black lines that converge somewhere up ahead in the distance, see Floating Mountain way the heck down the track, and so on.
I was lucky -- I can recall darn near every detail of my first run. I still get chills when I think of it. You may make scads of runs on the Salt in your career -- but the first one is absolutely the coolest thing ever. And -- when the starter says "Okay, the course is yours!" - then it's okay to have a tear in your eye. It's the fulfillment of a life's dream.
Yeah, you'll have fun at this. Welcome.
