Lanes and alleys are perfect subjects in which to find leading lines!  The alley does all the work, you just have to take the picture! I have a great love of alleyways and consider myself to be somewhat of an alley cat.  

Position yourself in the alley so that you are looking all the way down its length. This can be done from the end of the alley where you can photograph both sides, or you can highlight one side by taking the photography on an angle.  Be an alley cat in your photography today.

Don't hesitate to try different points of view and different angles.  No alleys?  No problem!  Try a street, sidewalk or bridge.
