To tightly seal the Texas border with Mexico would require

a National Guardsman posted every three feet.  Since the

border is 1,255 miles long, 2,208,800 Guardsmen would be

required.  To loosely seal the border (i. e., a National

Guardsman posted every 300 feet), 22,088 Guardsmen

would be required.  There are currently 23,580 National

Guardsmen in Texas.  Go figure.
