What counties are in this region?
I wonder what counties are considered part of the High Plains region? The reason I ask is that when researching the placement of Texas cities and towns, Wikipedia and other references will identify which county and state a place is in, but not which tourist region. For example: I deduce that Dallam County is in this region only because the county seat,Dalhart, is already listed here. However, it would be nice to know for certain which other counties are also here. I have spent ages looking at maps trying to guess which region a Texas town is in, based on the shape of the region matching the county border, but not knowing for certain that I have it right. - Huttite 21:32, 12 December 2009 (EST)
