This Saturday 21 February there will be an Open Data Day event in a Cambridge pub, the Panton Arms.

So closer to the station than the regular meetups.
I have only just heard about this. Someone from ContentMine will be there, and I'll go along. The event runs from 11:30 to 5 pm.
(ContentMine will also be represented that day in a Birmingham event: they are the people scraping facts from scientific journals. There are 60+ events worldwide.)
