This might not be the part of the hill country you were looking for, actually I think it is more along the lines of Edwards Plateau, but some people call it the hill country. I have hunted there for several years and even thought prices arestarting to get out of control sometimes you can come across a good lease at a resonable price, I don't know how often they update but at least it could get youstarted.Good Luck!!!!!!!!!!!!!!!
