One good thing about the "Whichever State" charges those 'day use' fees, it goes to the PARK, not to a 'reservation fee' that goes 'who knows where' ...
A lot of states charge for day use on top of camping, kinda a newer way to generate income. Most states have an annual pass that is much less if you stay enough days camping to make up for it.
For example: South Dakota charges a $6 (right, SIX DOLLARS) on top of the camping fee EVERY DAY - that's right, every day of camping. Unless you buy a $30 annual pass. SO, once you reach five days camping, the annual fee is covered.
IT also offers a seniors (SD residents only) half-price camping, but DOES NOT discount the $6 daily fee. SO, half-price PLUS full $6, unless you have the annual pass.
Only reason for sharing this example - read the rules for each state you camp in, and figure out the best way to use the fees system. Otherwise, it will sometimes catch you napping - and you'll pay extra for the nap, or course. :)
