It would have been great, but geez... Can't one just enjoy walking outside without having to pay for parking? We drove 3 hours and got there midafternoon looking to go to the boonies for some fresh air and a very low budget date, and the only option was going to be to pay for a whole day parking pass. While the pass itself wouldn't be considered by many "expensive" i didn't find it worth it after paying over $5/gallon at the nearest gas station...
I won't personally be looking to go back.
