Oops. A 911 call about an explosion in Northeast Texas led the Upshur County Sheriff’s Department to what was intended to be a secret cannabis-growing operation, TV station KLTV reports. The county dispatched first responders to a home just south of Gilmer, about 30 miles from Longview, after a witness called in Saturday to report seeing a fiery blast and a car leaving a nearby property, according to KLTV.
