My dear husband, who is much older than your son, just did the same thing. In February he called me and told me what he did. Well, to make a long story short, I just got my cycle license and I a Kawasaki. I haven't been out on the road yet, but I can feel the urge very soon. I didn't think at my age, that I would be venturing out into the cycle life. I'm willing to give it a try. He keeps talking about this certain Harley that he knows I would just love. My only problem with that is - spend that kind of money on a cycle, or - buy the sewing machine of my dreams. Which do you think I'd get more use out of...my point exactly!
I'm sure you raised him to be a safe person. Just trust in him and say a few prayers.
