I got this off another reflector. Even if you miss the deadline to purchase the lifetime senior pass at $10, it will still be a bargain at $80 later. If you go in person, it is $10, I chose to purchase mine online and save the drive. There was a $10 processing fee, still making it a bargain.
For those of us over 62 and U.S. Citizens or Permanent Residents, or know someone who is:
If you have lifetime Golden Eagle or Senior Pass, you are good.
If you do not, you can still get a Lifetime Senior Interagency Pass for $10. That price is only good through August 27th, after which it goes to $80. Even the annual senior pass is going up to $20. These passes are basically good for Forest Service, and Parks Service facilities, nationwide, and covers Day Use fees. It gets you a discount on other fees, but not necessarily at the concessions.
You can check it out and order online:
A small investment if you are over 62 and don't have a lifetime pass.
