T-Rex Natural History Museum
Smithsonian this museum is not - but it is charmingly quaint nonetheless. You get to do a lot of things that the Smithsonian probably wouldn't allow, such as taking photos with your head inside Sue's head. Yup - Mike, the owner, named the T-Rex Sue (she is a dainty female, after all). Other activities to be had here: touch petrified prehistoric poo poo and pick Mike's brain with as many questions as you can come up with. All of this for only six bucks per homosapien!
