My mother had new railings added to her porch. I've always liked the three railing look. It matches the house well - an old farm house with a classic red barn and lots of green around it.
My father always regretted the cement porch. It has lasted 35 years, probably more than a wood one would have, but it has needed moderate upkeep. I loved it as a kid on a big wheel. It's a big long straightaway with a 90 degree left hand turn at the end, perfect for Dukes style driving! I wore out the wheels in two big wheels over the course of a summer.
