Come join the second #editathon event of 2013, a nation wide weekend of mapping. Groups from all over the country will be coming together to improve the US map.
Saturday, April 20th, 2013 from 12-5pm at the Lucky Lab on SE 9th and Hawthorne. There is a room reserved so there shouldn't be as much noise.
All the details are on Calagator: http://calagator.org/events/1250463885
OpenStreetMap, sometimes called "the Wikipedia of maps" is a free worldwide basemap that anyone can use and edit. Even if you've never edited OSM before, you're welcome to join. Bring a laptop (and mouse, if you have one--it helps!) and your local knowledge.
We'll have a short "Intro to OpenStreetMap" talk around 1pm, and cheerfully provide assistance with setting up OSM editing software and learning how to add and edit features. Latecomers are a-ok!
