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.
An accessory before the fact is the one who intentionally helps a person commit a crime, but who is not at the scene. For example, assume that A asks B to murder C, and provides B with a gun intending that B use the gun to kill C. Two days later, B shoots and kills C. A is an accessory before the fact.
