Yes, Boston is quite well served by public transit, although last I knew getting from the airport required you to take a bus to the subway station. Use http://mbta.com/, in particular http://mbta.com/rider_tools/trip_planner/, to figure out which bus & subways to take. One-way trip is < 2 GBP. But to be clear, *I'm* not offering to host. I live 1.5 hours away from campus, which would make playing local organizer difficult. Northeastern University (embodied in Patrick Yott and Julia Flanders, both friends of TEI) is offering to host. Most likely the manager of the WWP or the coordinator of the DSG would be the local organizer. (And they're great.) I'm not sure what, if anything, we could do for a "TEI Day" on such short notice, though. From some point of view, it would be better to hold the Spring 2016 meeting at Northeastern, and throw a small 1-day conference around it.
+1 from me -- Boston is easier to get to than Raleigh and I've never been there... And I see from Mr Google that it has a subway station!
So does "quite viable" mean you're definitely offering to host, Syd?
