17. Keep The Trash Bins Hidden
This is one of my biggest pet peeves — when big, ugly trash cans are visible from the street, sometimes open with trash bags peeking out of the top. If you are forced to keep your trash where it can easily be seen from the street (or from anywhere really), put up a small fence, or perhaps even build (or buy) a garbage can storage shed. I think even a few lattice panels would do the job.
