I do believe the riding community is getting older, I'm not sure exactly why lots of reasons I guess, but I don't believe that money is one of them, The young people I know piss away money on a myriad of other things, so with redirection its as affordable to them as it was to me 40 years ago. Anecdotally my wifes daughter has raised her children to be risk averse, its funny because their father used to ride, but let me mention getting on a bike and the derision is instant, the boy isn't really interested in driving anything, let alone a motorcycle. The girl mentioned just after I got a new motorcycle two years ago, that she'd thought about getting her license, that one statement got so much ridicule from her mother she's never mentioned it again. I was hoping she'd do it for spite, even encouraged it, but no such luck.
I just chuckle at them and shake my head. Their loss, not mine with this and many other things in this life, that I hold dear. I try and quietly lead by example. I share my road stories, camping stories, hoping something may spark an interest, maybe they will come to their senses, maybe not.
Ultimately if they or other young people don't ever ride motorcycles I find it very difficult to GAF, its their life, I know I've missed things others held dear, too many lectures from the well intentioned. I'm convinced they are missing an experience that cannot be duplicated by anything, well bad sex maybe.
I think that's the thing really, WE think it's important, moving, exhilarating, and any other adjective you want to use, they don't. That simple. Will it all disappear, nope, change absolutely. Change is the only constant in the universe. In the mean time, I've got two sleeping beauties in the garage that need to wake up from a long winter slumber.
