This a great new museum in Milwaukee at the Lakefront. It has many hands on exhibits that change all the time and a really awesome aquarium! There are programs that can be signed up for as a family or just individual. Part of the year they even have an educational boat that docks there.The S/V Denis Sullivan, a 137-foot re-creation of a three-masted, 19th century Great Lakes schooner.It is also a scientific research vessel. The cost may seem like a lot at first glance, but if you live in or near Milwaukee the memberships offered are the way to go. You will want to go back a couple times a year, so they are your best bet!
