cover the saddle with a plastic shopping bag - lightweight protection from rain, sun, pigeon poop and covetous eyes.

or put some duct-tape on it - a small bit of tape would make it look battered and tattered.

drip some candle wax into the hex-heads - it would have to be a very special saddle for anyone to fight with that when there's lower hanging fruit.

i've got a "seat saver" cable but rarely use it. usually i just put a bag over the saddle. if saddle theft was a real concern for me i'd use the "seat saver", or get some security bits and a driver, or use an old chain and inner tube to "permanently" lock the seat rails to the seat stays.

if i had a saddle that was not just comfy but also expensive or difficult to replace, i'd take it with me.

access through the BB can possibly be used to secure the seat POST, but the seat...?

i can picture in my head... some crack-head who removed every bolt above the seat-post collar, unaware of a cable holding the seat post to the BB... and standing on the chain stays to gain leverage. he won't win, but you'll still lose.
