Keep it up, I sure am. Hope to get out west to train with some of the pros this year.I don't know, I'm 68 and one of my riding buddies is 81 we both ride Skidoo 850's. I'm not totally sure what you are asking but in my book, if you are out riding that's half the game. The rest depends on knowledge from the last 30 years and how well you apply it today. We still ride, maybe not as hard as we once did.
