What Are The Scientific Landmarks That We All Need To Visit?

Summer is coming up fast, and, hopefully, some accompanying vacation for you. What are some of the scientific landmarks that we should be checking out this season?

Maybe it's a national park, maybe it's the perfect star-gazing spot, maybe your pick is a museum or planetarium, or just a place with some scientific history. Give us your pick for the spots we should all visit this summer, along with the best few things to see there, and a picture to accompany it all.
