Horse trailers have more than one use, it seems, after US border patrol agents intercepted one with more than 1000 pounds of marijuana hidden inside.
Authorities valued the dope at nearly $US1 million.
The horse trailer, being towed by a Ford F-250 pickup truck, was intercepted by US Border Patrol agents at the Marfa checkpoint in west Texas, on highway 67, on May 30.
US Customs and Border Protection said the marijuana was concealed in the walls of the goose-neck trailer.
The drug haul was turned over to the Drug Enforcement Administration for possible further investigation, according to a release from agency.
It is unclear at this stage whether arrests have been made.
Authorities confirm that inquiries are continuing.
