For a year, I lived directly across the street from one of the boarding locations for the Boston Duck Tours. I lost count of how many times tourists waved and quacked at me.
But that fact made me no less excited when we discovered one of the amphibious WWII vehicles boarding passengers at the Roger Williams Park Zoo.
The vehicle tours around the scenic drive of the park, then dives into Cunliff Lake for a boat ride. And they let both my daughters take turns driving the boat, which most certainly never happened in Boston.
