The Senior Pass or former Golden Eagle (I miss that....) is going up at the end of August from $10 when you buy it from a ranger when you come into the park, to $80. For the rest of your life, they smile and hand you the brochure and are thrilled you came to visit.
Go see my man Jorge at the PEFO soon and be SURE to purchase it.
Or be more helpful and wait until the deadline and the money is used to help shore up the huge losses to every government penny sent to the park.
JUST DO IT!!!
