Do you lock your saddle to your bike?

Steve, from New York city (“I live  3 miles from where the World Trade Center used to be and 3 miles from Times Square.”) sent me this picture of his new saddle on his bike and I asked him about the chain around the saddle rails. Steve says it’s a pretty common way to foil thieves in the city.

I’ve spent my adult cycling life in Seattle and New Orleans. I have seen the occasional little cable for this purpose but I have never seen this bicycle-chain solution before. It got me wondering; how many of you feel the need to lock your saddle to your bike?

Please answer yes or no in the poll and if you want to elaborate add a comment to this post. Thank you.
