Just a little commentary on Boston.  Get the best Vietnamese sandwiches (I recommend the barbequed pork or barbequed beef, spicy of course).  The sandwich shop is in a cubby in Boston's Chinatown that has the best is on a one block street which runs from Beach Street to Kneeland Street, between Washington Street and Harrison Avenue.  Buy ten, get one free, not the best deal I have seen, but very good sandwiches.  Go ahead and eat a couple, you will need the energy for the Freedom walk, which begins at the Boston Commons, a great place to eat your sandwiches.  It proceeds to take you by the State House,  the Quincy Market, Faneuil Hall and Quincy Market, Little Italy (the North End), Revere House, North Church (Revere's lantern display site),  Bunker Hill Monument, Charleston Navy Yard and the USS Constitution--free tours of several ships.  Stop at each of the cemeteries you pass, the picture above of Mother Goose's grave is from the first cemetery one passes upon leaving the Commons, and view graves of people you have only read about that lived hundreds of years ago and helped shape our country.  There is a half-price ticket place for the theatres in Quincy Market.  Another great walk, much shorter, starts at the Federal Courthouse, across the pedestrian bridge, which is anything but pedestrian, and after stopping at the incredible seafood wholesaler just to see the size of them things (they have to duct tape the claws over the rubber bands on the lobsters' claws and the dungeness crabs look like sea monsters), go through the gate just to the right of the end of the pedestrian bridge, waterside by Rowes Wharf.  Just stay by the water at every opportunity.  One will wind in and out through the marinas and piers.  They are continuing to improve this walk.  Great views of the sea lions for free at the Aquarium as you pass near Columbus park.  There is a good bathroom stop on the second floor of the Marriott here, by the bars and restaurants.  The walk actually ends pretty much near the Old North Church--also near a great Italian bakery (yep, the North End is Little Italy, and it shows).    I haven't found a restaurant in Boston that I really liked the food and the prices, but believe me, I am still looking.  Don't miss the shopping on Newberry Street.  Lastly, one can get some pretty good hotel prices downtown (relative to normal, and notice I didn't say cheap, on weekends, especially holiday weekends (one Thanksgiving weekend I got two nights, Fri and Sat, with free parking and 2 free buffet breakfasts each morning at the Radisson by the Commons/theater district for $150 total, been watching for it again, without success!  I realize that some readers will say that is still quite a lot for a room, but when the usual price, check it out, is $250-300 a night).  And lastly, every Saturday during reasonable weather (above freezing), there is an incredible farmer's market, which runs all day long, which will beat any supermarket specials you can find.  It isn't really farmers selling the produce, the produce may be seconds, but on my recent 11/6/05 trip, I got three packs of romaine hearts for $0.75, head lettuce and avocados 2/$1, granny smith apples 6/$1, whole cases of yellow and zucchini squash for $3, and much more.  I am still (on 11/14) eating fruits and vegetables from that trip.  My commode isn't anxious to see me go again....sorry, had to say it...lol.
