Last Friday, Intel Folsom hosted a mapathon with the Missing Maps Project. Estimated attendance was 56 mappers, plus 2 volunteers from the Gold Country Red Cross and 1 volunteer from Intel to answer their questions. The work was done on HOT project 5378 from roughly 2-4pm Pacific time (21:00-23:00 UTC). This was the second such event, and it is anticipated that we will have another one, though the date is not yet known.

Edit: it was brought to my attention that one participant did not sign the photo release. I will post an edited version when I have permission to do so.
