Well it does exist! Mount Rushmore is a pretty impressive spectacle. Like all giant things, it's sometimes hard to grasp the enormity, even when you're there. So while I won't say it took my breath away by its size it was still clearly impressive and definitely exciting to see in person. The whole presentation is surprisingly restrained and tasteful. For a Big, American monument of gigantic presidents that was mostly created with dynamite, the entire place had a surprisingly understated presentation. There wasn't any theme park-type stuff anywhere to be found.
One restaurant/cafe, not selling carny food or deep fried meats on sticks. The gift shop didn't offer giant gray foam hat where your head goes in place of Jefferson's (I was prepared to spend up to $30 for that foam hat!). There wasn't a big cardboard cutout where you could pose behind it putting your face on Mount Rushmore. It just felt... classy. Which caught me totally off guard. It was a pretty respective place and I'm glad it really does exist.
Oh, and by the way, you can see it from the road, so you really don't even have to pay unless you want to get closer.
