Tonight I want to throw an idea at you that will help you find painting locations. It will make lots of places paintable that you might have walked by before. Stop looking for a subject to paint.
Look for shapes, not objects when hunting locations. There are lots of places that have good shapes and a picture with good shapes is going to work, no matter what it's subject is. Now you are seeing like an artist and not a writer. Even when you do find a subject that's a natural, an old barn or a picturesque mountain view, stomp around until you get the best arrangement of shapes it offers. Often when a picture goes wrong, it is because of the failure to make good shapes.
The paintings on this page are by Eugene-Louis Boudin 1824-1898 courtesy of the Aethenaeum.com. Boudin was an expert at this, his paintings are arrangements of shapes and colors that set one another off. If you squint at the marketplace picture above I think you will see what I mean. He has also arranged the lights and shadows to make the picture work.
Harbors are often picturesque but Boudin has designed this one. He has, for instance, grouped his objects into large simplified darks that make big shapes rather than indicate individual hulls of boats. Then he threw a white hull down on top of the whole show. Maybe it was there, maybe it wasn't. Who knows? But it is a great device. That strong contrast at the subject matter arrests the viewers eye. Again squint at this image and see the bold simple arrangement of a few lights and darks that he has used.
Look at the irregular wedges of black that Boudin has built his design. Also notice the nearly divisionist "hatching" he has used in that rooftop. It almost looks like Childe Hassam's handling. Because he is painting an arrangement of shapes rather than a narration of specific characteristics of the place he is free to summarize things and work with a more artistic handling.
