I just finished adding the Tiger 2009 area polygon shapefiles for California. The data includes most parks, national forests, cemeteries, commercial areas, some schools, colleges and universities and more. I tried to remove the larger parks and areas to not duplicate existing areas. But some of the smaller parks were repeated and need to be manually removed. Also Tiger uses a weird set of abbreviations which I documented on the [[TIGER 2009]] wiki page. I corrected some of the later ones by opening the OSM file in a text editor and then doing a find and replace for each one. I uploaded all the counties except for Santa Cruz and Los Angeles which have already had imports done in them or have already been mapped. I added the points and water files in the bay area. A lot of these repeat what is on the ground, so I am going to let others add the other ones in their counties if they want. If anyone in the U.S. would like to upload data for their counties but doesn't know how to use the java shp-to-osm, let me know and I can email you the OSM files you can upload in JOSM.
