Cheap security for screen door
My beach apartment complex allows renters to put up screen doors. This would be great because it allows a wonderful breeze through the whole apartment. Lots of people have them. This is in a very safe area of the city but just doesn't seem wise to have my front door open with just a screen door preventing entry. I have to pay for the door and I don't want to buy an expensive security door. What could I add to make it safer? Any ideas?
