If you're in Boston for the convention, and you were a Deaniac back in the day (or a Democracy-for-America-phile these days) then check out the Dean volunteer appreciation event at Hurricane O'Reilly's. Gov. Dean will give a short talk, and the rest of the event will be an informal reunion with other Deaniacs (or DFA-philes) in town.
It's 150 Canal St. in Boston, 12 noon - 2 pm on July 28. For out-of-towners, this is very near the Fleet Center; the closest open subway stop is Haymarket, on the Orange/Green line.
