Fibers are like tiny little rods or tubes-much longer than they are wide. Just about any fiber that you can think of is a polymer. (I guess that if it's a metal, it's called a wire, not a fiber!). Fibers can be natural-from plant or animals, or synthetic-made by people.
Accessory uses and structures. (A) A structure or use which is clearly incidental to a principal structure or use, and is located on the same lot with the principal structure or use, is an accessory use. All accessory uses are subject to the restrictions in this section.
