National Park Fees

I tend to get the annual pass, even if it might cost me an extra $10 or $15 above the parks I intend to hit. It's convenient, and having it encourages me to stop at more places along the way. It's good for a bit over 12 months, so who knows, I might get some more use out of it before it expires.

I never knew we could show our receipts and pay less for the annual like some people are suggesting. But.... would I find all my receipts when I needed them??
