The Boston Duck Tours are good anytime but they are little more fun when there are more people on the street. (Better weather makes for passing more pedestrians and possibly more quacking) Everyone should go at least once. I enjoyed my second time (with out of towner family) just as much.
Besides we don't loose that many
I had the pleasure of driving past the swath of destruction the day that the soda bottle rolled under the brake pedal of a Boston Duck just after it got off a Storrow Drive exit. Their insurance rates went up that day.
And to be fair, on the sinking, it was the other guy's fault.
I would go again but if the driver said "everyone get out!" with a barge nearby, I'd be one of the first into the water, not the ones who thought he was joking. Who doesn't like a little excitement, Right ?
