Coming In To Boston

Entering Boston on Interstate 90.  The notable buildings visible are (from left to right):  The former John Hancock Tower -- now known more prosaically as 200 Clarendon -- the tallest building in New England.  It was infamous in the 1970's because it had the disconcerting habit of ejecting its 4' x 11' windows and sending them crashing to the sidewalks below.  The Prudential Tower (fondly referred to as "The Pru"), which is the second tallest building in Boston, with a fabulous view over the city from its 52nd floor Top of the Hub restaurant.  The shorter, mirrored, rounded top structure to the Pru's right is commonly referred to as the "R2D2 Building" for obvious reasons!  And finally the tower under construction at far right is One Dalton Street, which will be a Four Seasons Hotel and condominium tower when it opens in 2019.  It will become the third tallest structure in the city when it is finished.

Extra shows the rather confusing sign showing the exit you need to take from I-90 to get to our apartment!  North? South? What?????
