Yep! It's all Legos.

My sister and her boyfriend are visiting and wanted to see Legoland while they are here. It is a pretty amazing place. They have created replicas of some major U.S. cities built to scale completely out of Legos. I found out from one of the park guides that the sun here in Southern California really takes a beating on the exhibits so they are constantly being rebuilt. Each creation can take 300 hours to create. The park has rides and amusments that are pretty much for the littlier kids, but us big kids found lots of fun photo ops :)
