shedd aquarium: Is it a thing two 18 year olds would like? Is there enough to do from like 12pm-5pm or does it only keep a person busy for a couple of hours? Any other info would be great! Thanks!|||5 hrs is a stretch but the aquarium is on the Museum Campus. If your interested in Astronomy go to the Adler Planetarium. Natural History, including the largest tyrannosaurus rex, mummies, and many other things, is found across the street at the Field Museum. The Art Institute will amaze you. It is farther away but you can hike there through Millenium Park. Those are good nearby places in all types of weather. If it is a sunny day why not walk through Millenium Park...just head for the skyline. You can spend some time there enjoying the sculptures and lunch at the Park Grill: http://gochicago.about.com/od/chicagomus鈥?/a> http://www.millenniumpark.org/ http://www.millenniumpark.org/parkevents鈥?/a>|||Here is a list I live here: 1.
