We’re all familiar with the whimsical-looking duck boats that constantly drive around Boston. But have you ever actually taken one of these duck tours? Well, here’s your chance. Santander has reserved the entire fleet of duck boats for Friday, October 18 (that’s tomorrow!). Beginning at 9:00 AM, the public can join free duck tours. No tickets or reservations are required; simply show up at one of the three ticket locations (Prudential Center, Museum of Science, or New England Aquarium). Show up early as spaces are limited on the boats. Thanks to Boston On A Budget for alerting us of this awesome duck tour promotion! You can get more info about the free tours here.
