Oish. Really??

So camping isn't as cheap as I might have imagined, especially when you get hit with transaction fees PER NIGHT when you make a reservation.  But really Idaho?  Places we've stayed are all even dollar amounts per night.  Not Idaho.  Lake Cascade was $18.78/night (c'mon guys), and Benewah is $20.14.  I'm good at math, but that's just absurd to put me at a pay station and ask me to figure out a 5 night stay.  And it's different if you're a resident (still not even dollar amounts, though).  Oh, and if you have a park pass, at some you subtract $5/night, but others you pay an additional $5/night if you DON'T have one.  Crikeys, guys, get it together.
