The folks from the Esri Dev Meet-Up Team (@AmyNiessen and @geeknixta) will be back in town on February 7 for a winter Esri Dev Meet-Up at the Bell in Hand in Boston. I’ve been to a few of their events over the past couple years and they are always a good time. Usually there are a few good GEO and GIS presentations and Esri provides some food and drinks (nice!).
If you are in town and are available check out the event. Details are available at the Meet-Up site.
