Being a native of South Dakota, I found that tourists were given the short end of the stick. Tourists are directed to the commercialized sites such as Mount Rushmore, the Cosmos, Reptile Gardens, and so many more. There is so much natural beauty to behold in the Black Hills, Hippie Hole, Boulder Hill, and Pecker Rock, for example. Pecker Rock is a natural rock formation just around the corner from Mount Rushmore. To find this phallus shaped rock, drive toward Mount Rushmore from Horse Thief Lake. Pecker Rock is visible from the road off to the left. There are no markers for this natural phenomena since nobody can own it to make money off of it.
