I currently live less than a couple hours away from South Park, so I screeched at my boyfriend to pull over the car when we drove through on our way to Denver so I could take these pictures.
There's not much there, a few gas stations and diners. The South Park of the show has a lot more going on than real South Park. There's no True Value, no plane-arium, no water park, no lesbian bar (I'm assuming), and no Tom's Rhinoplasty.
However, the spirit of South Park in the show is pretty accurate. Very cold (now I know why those kids are always wearing hats and mittens), VERY windy, just your average quiet little redneck mountain town.
Although we did nothing there but buy some snacks at a gas station, I feel a special connection with Stan, Kyle, Kenny, and of course Cartman after seeing in person the setting for all their shenanigans.
