I generally consider the Hill Country to be a little to the west of us...Kerrville, Ingram, Comfort, Vanderpool, Hunt, etc. Those areas are certainly hillier than my area, although many would consider Driftwood to be in the Hill Country.
As soon as I get a new computer I'm going to install PS and play around with a project like this. Maybe I can figure it out.
