the Arlington drop off point for Brookfield is a 30 minute walk from Davis. It is also on the 87 -- the stop is across the street from the drop off point for the Brookfield CSA. The Cambridge drop off is an uphill haul from Porter Square. Depending on where you live, one or the other might be more convenient for you, but the Arlington drop off definitely has the advantage of the bus. It's a very nice CSA, but maybe you want to pick somewhere closer (they have great pick your own, for example, but how often can you realistically get out to Amherst to pick your own?).
