If you want the ultimate new perspective on the city, the best place to get it is on the lake. Unless you're a Lake Michigan boater, looking at the city from out on the water is a rare treat. Sailing on the S/V Denis Sullivan, which makes its summer home at Discovery World is an incomparable way to enjoy that view. But, while on board, you can also chip in some elbow grease and help the crew raise the sails.
