Very nice Don. I followed this back to your gallery and also saw the color shot of the back of the woman on the train. Even better IMHO - your typical ability to find beauty where few of us would ever notice it.
I love color, and most of the photography I have done in my life time has been on color slides, which are now languishing in files neglected and forlorn. However, there is something compelling about B&W. I don't know what that is, but there is no doubt about it, B&W is special in its own way.
