The South Texas Brush Country is roughly defined as the land south of a line drawn between the cities of Corpus Christy, to San Antonio and then to Del Rio. The majority of Texas' trophy bucks come from this region, and the heart of trophy buck country is a triangle formed between lines drawn from Laredo, to Dilley and then to Eagle Pass. See my page showing a listing of all B&C Texas bucks and where they were killed.
The area in Mexico that is best noted for trophy white-tailed deer is an area 50 to 60 miles wide south of the Rio Grande River between the Texas cities of Laredo and Eagle Pass. See my page showing a listing of all B&C Mexican bucks and where they were killed.
