MM - Leading Lines

I love this narrow cobbled street which I've blipped on previous occasions but I thought it would make a nice leading line for today's MM challenge.  The day was damp and grey, although not quite as dark as my shot would have you believe and I have to admit to darkening the image in PS.

I've got a set of ND filters and "big" and "little" stoppers, but I've never owned a Polarising filter until today.  Other members of my club all own one and they convinced me that I really ought to have one  -   of course now I'll have to wait for some good light before I can try it out.

Thank you for the kind response to yesterday's squirrel shot, it's very much appreciated.
