Once a year, the Shedd Aquarium hosts a Spring Fling where you and your family can sleep overnight in the aquarium. There’s dancing, which may include Raffi, and that might be excruciating. Also, there will be other people’s children, which sucks. And they probably won’t let you wander the halls and stare into whatever tank you want without ever sleeping.These drawbacks aside, I nearly tried to conceive and birth a premature baby just so I could have an excuse to go. This looks fun as hell.
