Turning 43 this summer; started riding at 9 on a YZ80 and busted myself up on several occasions
Took a hiatus from the dirt for ~31 years and only had street and track bikes; I'd guess 100,000+ street miles and 11 years on the track now.
My awesome wife surprised me with a YZ450 as an early 40th gift - rode that bike 3 times until I realized it was going to kill me...lol. Sold that and picked up a KTM 300 and put 110 hours on it in a year. Had a fellow member clue me in on GG (firffighter) and I'm hooked. So much so that I sold my wife's orange 250 and I'm on the hunt for another 200
I've had so much fun getting back into dirt riding that my wife followed suit, my 66 year old mother-in-law picked up a CRF150, and my brother-in-law is on the hook to get a bike too. We have two boys (2 & 4) who really don't stand a chance when it comes to bikes - we've been hauling them to the track since they were born and now we drag them out to the woods to camp and ride.
For me, there's nothing better than riding on the trails.
