Yet somehow, the person in the toll booth option has regularly been the cheaper option than paying these immense fee's to obviously corrupt government contractors.
How many web site designers and colocated machines does it take to run a freaking reservation system that probably gets a couple million reservations a day.
Plus, if done correctly a large initial investment and then a trivial amount of work to keep it running, where the vast majority of the work is the local parks/etc changing the state of campground availability/etc.
Put another way, everyone wants to be the credit card companies that have successfully gotten massively rich on a system where they are taking a percentage of the total transactional value rather than a trivial flat per transaction fee. And this model doesn't belong anywhere near public systems because those public lands exist for the "public", the majority of which can barely afford the gas to get to the park, much less funneling more of their meager resources to a fat cat government contractor.
$6 is close to an hours work for someone making minimum wage.
