NPS Senior Pass

Several years ago . I should say over tens years ago now, my wife and I went to Yosemite National Park. We were entering on the north gate on Tioga Pass, California State Route 120, anyway I had my Handicapped Placard laying on the dashboard of our P/U Truck. The Range gave me a form said to fill it out and put my CA. Handicapped Placard number and my CA. Drives License Number and sign it and she gave me a Inter-Agency Pass that was supposed to be good for life. I know it was $10.00, even if I have to buy another Senior Pass I will because $ 80.00 is a lot more reasonable than what it costs to belong to some of these camping clubs, Thousand trails, KOA, Passport America. Just my opinion. I guess maybe I should go and look at my Pass and make sure I still have it in the RV, i keep it with the registration card.
I love to boondocks and paying $5.00 a night is cheap at twice that price.
