Do any members in the Los Angeles area know of any place where I can buy small quantities of fiber optic cable? I prefer not to have to order it online.
Both Allied Model Trains (in Culver City) and The Whistle Stop (in Pasadena) have carried small portions for train applications. I would call first. Also, try Kit Kraft (Studio City) and see if they have any in stock. (Plastruct makes a couple of different sets and they may carry it.)
