Co-owner Troy Moore prepares packaging at the "Oregon's Finest" medical marijuana dispensary in Portland, Oregon April 8, 2014. Over 20 Oregon cities and counties are moving to temporarily ban medical marijuana dispensaries ahead of a May deadline, reflecting a divide between liberal Portland and more conservative rural areas wary about allowing medical weed. Portland, Oregon's largest city, already has a number of medical marijuana clinics and has not moved to ban them. Picture taken April 8, 2014.
