I'm going to start adding bugs to Mapdust as I find them while on the road trucking. Given the generally good availability of aerial maps and GPS traces in the areas I'm driving in, these should be fairly easy to locate for an armchair mapper. Most of the locations will be in eastern Oklahoma, with some locations in adjacent parts of Arkansas, Missouri, Kansas and Texas. See http://www.mapdust.com/?zoom=8&lat=4164934.6421&lon=-10808329.62579&layers=B0T for current bugs in this region.
OSM is being actively consumed by truck drivers in this region, and there's a *lot* of TIGER data needing review, so your efforts will definitely be appreciated.
