54 y/o, 6', 190 lbs, in good shape, have about 10 hours on the board over 7 days, and skated a lot . . . 40 years ago. I've been taking my hard knocks on a community softball field, and have total respect for this board.
I have a full face helmet, padded shoulder football tee shirt, and padded elbow/forearm knee/shin guards on the way.
I was a profession firefighter/paramedic 25 years ago. The Cliff Notes of my experience is the following:
Moving Human Being vs. Stationary Object = Human Being Loses Every Single Time
How fast you're moving, along with how unprotected you are, only determines how bad you're going to lose.
There is NO WAY I'm hitting the streets until the rest of my gear is here, and my calf muscles are fully retrained and have the stamina for board sports.
I'm not somebody's mom, but how some of the adult males I've been seeing vids of, blasting down a paved road in shorts and a tee, with only a ball cap, with a selfie stick in one hand and looking at their phone with the other - I just don't get it.
I was up, stable, and running at 15 mph within 15 minutes on grass, but could just tell there were so many nuances with the board that would need to be learned, that I needed to just slow the F down and stay on grass.
I'm not scared of getting hurt, I'm scared of getting hurt and not being able to ride this thing. It is as life changing as I suspected when I first saw it.
If you're new to this thing, as I am, get some gear, keep it slow, and stay on grass - the glory days can wait. The saddest things I've been reading on these sites are about people taking themselves out of the game.
At this point, I'm not willing to blame the board for anything - the thing is so finely tuned that it responds to your mere thought. When I've eaten it, my head was usually wondering.
. . . just my two cents, I love this little thing.
