Adults and children alike all adore the Chicago Field Museum. And if your child is a dinosaur lover, then one visit to the Field Museum and they will be instantly hooked! The Field Museum is the home of Sue, the largest and best preserved T-Rex. She happens to be a bit of a Chicago celebrity as well and kids just can't get over the fact that Sue is 65 million years old. During the summer, kids even have the opportunity to spend the night at the museum, amidst the towering dinosaur skeletons, to finally see if they really do come to life at night.
