For those of you who do not know, the month of June is nationally designated as Pride month in memory of a police raid on the Stonewall Inn in NYC in late June 1969. This raid set off a series of protests and riots advocating for LGBT rights, and is considered the impetus for the current LGBT rights movement. (There's lots of pretty good info about the history of Gay Pride on Wikipedia.)
There are many Pride events to attend in Boston, you can check them out on www.bostonpride.org. All are welcome to all events – you don't have to identify as LGB T to have fun at Pride events or to recognize Pride as an important part of engendering equality in our society.
