The city of McMinnville is once again offering Christmas tree recycling for evergreen trees.Some changes have been made.“We only have one drop-off location this year,” said city landscape manager Hank Patton. “In the past, we have offered up to three locations. There weren’t enough trees donated so we dropped down to one.”This year’s donation location is McMinnville Civic Center at 500 Garfield Street in the front parking lot.
