Late in June I'll be taking a trip from Grand Haven to Chicago. This will be my first trip into the windy city via boat. Any tips from the CSR folks that have been there, done that? My crew will consist of three humans under the age of 10 so I need to keep everything PG-13 rated. I'm looking forward to a dinghy ride through the locks, exploring downtown a bit from the water. I also plan to walk over to Navy Pier and likely the "bean" in Millennium Park. Otherwise that's about it. Any other must-do activities relatively close to DuSable? Thanks in advance for any tips!
