theres should be plenty of leases available withing a couple of hours driving any direction from San Antonio. Your right in the Hill country area. You shouldnt have much trouble finding a lease in several different price ranges, or day hunting too for that matter. There is public land in several areas, some of it type 2 land, that you only have to purchase a permit and license. And there are draw hunts at the Wildlife management areas. The public land is usually pretty crowded the first couple of weekends only and then it dies down considerably.
by the way, thanks for the plug moose
