PRESIDIO - Half a ton of pot, that's what a bust in Presidio uncovered.
Authorities arrested 2 men late Saturday night at a border checkpoint south of Marfa, along Highway 67.
We're told the men hid the drugs in a compartment of a horse trailer.
The street value of the pot is $780,000.
Both men are U.S. citizens, but neither have been identified.
The case and the pot have been turned over to the Drug Enforcement Agency.
