Opening My Eyes To All The Possibilities

Today's Mono Monday theme was "Openings" and I immediately thought of where I wanted to end up to get my blip.  I did get there, but along the way , I couldn't resist snapping a few (okay,several) shots of other openings and I realized that it isn't necessarily only the opening itself that matters, but what is around it to draw the eye toward it.  That's how I came to spot this drain surrounded by lines of light and shadow, running into and out of it like water and why I chose it for my blip!
