having grown up in boston. all of the prior suggestions are excellent ^^ but how come nobody mentioned the swan boats at the public "gahden" . yeah, it's corny but it's a fun little ride (http://www.swanboats.com/new/welcome.shtml) and i even remeber when adults were 25 cents and kids only a dime-late '60's people-i'm not THAT old

i'll also add that if you're a history buff, explore the state house on beacon hill (the hall of flags is pretty cool) and a walk on beacon hill to look at homes with the "purple windows" (glass is so old that it has turned purple tho some folks "cheat with purple curtains behind clear glass)

now as to the blessed red-sox (hey, i can now die a happy goalie ), according the the 2007 schedule, they are home april 20-22 vs the yankees and 23-24 vs toronto. you should at least try and take a tour but if you can go to a game, it would be even "bettah", tho trying to get tix to a yankees (arch-rival/anti-chri$t) series is pretty much next to impossible but ya nevah know.

lastly-check the weathah right up until the day before you leave as the old saying in boston is "if you don't like the weathah, wait 5 minutes"(.....i remembah snow in may and 80's in february)

oh and lasty, we don't have an accent , it's just that the alphabet only has 25 lettahs-there are no r's in the english language

enjoy your trip, you'll have a blast
