More than 9,200 pot plants being grown illegally on two islands in the middle of the Colorado River were seized Thursday in a bust by a Western Slope drug task force. The pre-dawn raid by more than 50 local and federal law enforcement officers approaching the grow on foot and by boat also resulted in the arrest of two of three armed men guarding the operation about 100 yards from Interstate 70 in De Beque Canyon. “It was right next to the freeway,” Denver DEA spokesman James Gothe said.
