So what trip to Baltimore is complete without riding a duck? Yes, I said riding a duck. No, not the little feathered things that quack, but one of the fleet of amphibious vehicles that you'll see cruising the streets of downtown Baltimore. These things are amazing. Climb on board and you'll take a tour of the streets of downtown, but it doesn't stop there. These are amphibious vehicles, so you're going right on in the water hon! An absolute MUST DO when in the area. Oh, and the duck whistles shaped like a ducks bill and providing an pleasant yet annoying duck call will be a hit with the kids for sure!
