The sights and sounds of the urban city can differ greatly from those of a more rural environment. While one area may be more pastoral and peaceful, scenes found in any of environment can hold a certain beauty.
Although I agree that scenes of a serene lake, colorful sunset or brilliantly colored leaves or flowers are very pleasing to the eye, I also find architecture and industrial items fascinating. A brightly colored cardinal sitting on a limb filled with deep green leaves will catch my eye and have me reaching for my camera in an instant. However it is more unusual items, the everyday things that forces me to look deeper at the subject, and proves to be more challenging, and for me, sometimes more appealing.
At first glance, a utility or man hole cover seems dull, certainly not something overly aesthetically pleasing. But upon closer inspection, items in the vicinity or the workmanship of the item itself can be visually appealing.
Sometimes it is the everyday things, the things we take for granted that can hold a certain beauty. A light pole illuminating our way can give us a sense of security. A railing or fence protecting us from a fall may not be the first thing we think of when considering a photo opportunity. But, it is these drab and sometimes dull items help to make our lives easier and safer, and I find that there is beauty in that.
