Went here with a few friends on a recent trip to Boston on the recommendation of a trolley driver. After waiting in line for what seemed to be most of the afternoon (as everyone had to remove pretty much every piece of jewellery, watches, etc. for the security check, which, I might add without exaggeration, is unquestionably more stringent than at Logan Airport), the attraction itself was mediocre at best. We were there less than 5 minutes and left. Good thing it was free.
