All the green stuff in a tractor-trailer rig stopped in northern Arizona wasn't spinach.
Highway Patrol officers found 1,000 pounds of marijuana in the big rig carrying spinach after it was stopped on eastbound Interstate 40 in Flagstaff on Tuesday for an equipment violation.
The Arizona Daily Sun reports that officers took the truck to a Wal-Mart store to use its loading dock to remove the marijuana from the trailer.
The driver and another person were arrested and jailed on suspicion of various drug charges. Their identities were not released immediately.
The Sun reports that authorities are investigating where the marijuana shipment originated and where it was headed.
