A person is not very smart when they know they live in an area shared with bears and they leave food outside. They have been seen on our driveway just outside the garage door. Because of that, our garbage stays covered in the garage. I never leave anything on my porch that even smells like food, although I cook out there sometimes. One of our neighbors made that mistake and came home to find all the screen missing and her porch destroyed. Recently a bear opened the fellowship hall door of a local church and was in the back area of the church. Out front there was a wedding rehearsal going on in the sanctuary. Luckily enough nobody went back there. When the bear decided to, he went out the same way he went in. There were witnesses.
