Just wanted to remind those on the forum that the price for a Lifetime Senior Pass for the National Park system will be going from $10.00 to $80.00 soon. I am not good at links, but if you go to nps.gov they explain how to get one. We got ours by going to a local National park and filling out the paperwork. $10.00 cost in person. You can apply online, but it cost another $10.00 Great way to enjoy our great Park system.
