I want to put a gate across my front walk. The walk is straight, about 15 feet long to a wide 6 step staircase, onto a large porch. The house sits somewhat close to a street with a mall in the center. A short street deadends just to the south of the side of the house. The house is a large Victorian with 6 apartments. What finials should I use in the iron gate to protect and yet not block good 'stuff' from entering? Thanks.
