Yesterday afternoon, I was in Bethesda, Maryland, just outside of DC, for a meeting, parking six blocks away. The meeting happened to be at the same place (Caribou Coffee) where we met for an OSM mapping party in November 2009. (osm.wiki/Bethesda_Mapping_Party) At that time, we collected some POIs for the area north of the coffee shop.

This time, I got POIs for the main shopping area to the south of Caribou. Between Mazpen POI Collector app and jotting down some notes, I collected & added ~100 pois while walking. Also, there were some things to update. (new Taylor Gourmet, Vapiano; Austin Grill and some other places gone now)

Since then, I've filled in nearly all of the buildings in Bethesda, using aerial imagery and the map looks completely transformed.

There's still lots more to do, collecting more pois, addresses, and other details from on-the-ground mapping, and maybe another mapping party. ;)
