If you live long enough, you can buy a lifetime National Park Senior Pass...
they raised the price from 10 bucks to 80, a couple of years ago, though. But still, all you have to do is not die and eventually you can buy one. Of course, you'll also have to stock up on advil, adult underwear, reading glasses and ride a bike suited for geezer. Maybe a Honda PCH or ....?
And OMB is right, Hwy 108 is much better than Tioga, or take Hwy4, which is even more fun than Sonora Pass.
Everyone's Idea of a Geezer Bike is different. Now get off my lawn. :afm199
