If the step is too far (icy decks become a problem this time of year and my knees are getting older) add a railing. A pull-in line also helps.

The railing is welded from 1 1/4-inch square tube. It is attached with lag bolts, and the top is reinforced with a 1 1/2-inch steel strap around the piling. The paint has a non-skid finish. About 2 hours of cutting and welding, followed by painting and installation.
