Latest imagery available for the area's already in Bing and it's 2011-2013 vintage stock at this point. Between the renaissance of Tulsa and many small towns in the region, 1 new town built and incorporated, and 3 or 4 towns that went bust and are in the process of being torn down and recycled for materials, that imagery's not far from being unusably old.</div></div></div></div>
