The trailer was taken from the organization's headquarters in the town of Galt, not far from the state capitol in Sacramento at about 3:10 am Wednesday.
The California Highway Patrol, which is investigating the theft, says the trailer is a white Wells Cargo double axle box trailer, with license plate number 4KJ1127. The suspect's truck is described as a dark-colored, long-bed pickup truck with an extended cab.
If you have information on the trailer or the truck, you are asked to call the CHP at 916-861-1300.
The State FFA Leadership Conference is to be held in Anaheim in the coming days, from April 22nd until April 25th. The trailer was to head from the headquarters to Anaheim soon.
The trailer contained 8,000 Disneyland tickets were to be distributed to the attendees. Because the tickets may be invalidated by Disney, the CHP is telling people to use extra caution when buying passes from unknown sources.
