Do you have boxes/bags of material that need to be shredded (as opposed to just recycled, like advertising)? Gladstone is having their annual Shred Day on Saturday, May 10th from 10am - 2pm at the Gladstone Civic Center, 18505 Portland Avenue. You can bring up to 10 boxes/bags, but you will need to take the boxes/bags back with you. 
The police department will be taking old medications, including prescription, over-the-counter and pet meds to destroy. And if you forgot to have REV pick up any old electronics, appliances (small), or other items like old Christmas light strings for the Kraxberger Robotics Club, you can bring these on the 10th too. 

Register for this if you want a reminder the day before.
