From little white picket to barb wire, wire mesh, split rail, or chain link. Wrought iron, wood, bamboo, aluminum or vinyl,... Fences are used to define area boundaries, keeping people or animals out or in, for privacy or protection.
Post your photos of fences of all types. The fences must be man made. No tree lines and rock outcroppings allowed, and no stone or brick walls, although brick posts within a fence are allowed.
EDIT: Pictures of gates will only be tolerated if the focus is on the fence attached to it. If the gate itself is the overwhelming focus of the photo it will be considered off topic. When in doubt, try not to include the gate at all!
