Move over, Chicago: The BSA is partnering with The Charles Riverboat Company and Boston By Foot to offer the Charles River Architecture Tour–the city’s first seaworthy exploration of its historic and contemporary architecture. The 90-minute boat tours will depart, rain or shine, from the Cambridgeside Galleria Mall dock (100 Cambridgeside Place, Cambridge). Tickets are $20 ($15 for BSA and Boston By Foot members and seniors over 65; $8 for children under 12).
