Don't remember the guides name, older about 65 or so, proably retired. Kinda thin male. Boston Museum of Science.
But, having been there on more than one occasion, it is not just him, seems they all say the same thing. Kinda like canned ham.
Is he friends with the short fat guy who gives tours there on Wednesdays? Because I know that guy and he says the old thin guy is a known crackpot.
This is the Boston Museum of Science that's located on the Charles River, right?
And approximately when was your last visit when you heard the guides say this sort of stuff? Season of the year and year will be close enough.
Were these paid chartered tours, or the free public tours conducted by the guides who are available daily? Or both?
