bumping boston to ask what are the best or goto dry spots/parking garages etc. around?
There are some good ones outside of the city, but they are well-guarded and well-kept secrets. That said, the Prudential Garage (e.g. at Prudential Mall / Copley Sq.) is well known. But, you could be there for 60 seconds before a bust, or quite awhile. Roll of the dice.
