...That said, if you really want to make an "actual difference", YOU need to get your hands dirty and make that difference. Clubs are maybe the best option for doing just that as many work hard with entities like the Forest Service or BLM and to maintain existing trails. However, with the advent of social media, clubs have been falling out of favor and many of they are dying. Worse, some are starting to advocate for the closure of some trails, as a kind of sacrifice and with the hopes of keeping others open. Also, some make it so that only THEY can run the trail and I personally find both to be abhorrent.
So, for me personally, I just try my hardest to enjoy what's still available now and for as long as I can. Certainly, I'm not getting any younger.
Of course, this is just me.
