It’s plain and simple, I need exercise! One way for me get some exercise when traveling is walk the stairs at the hotels. I take the elevator with my bags but after that I usually walk up and down the stairs. I’ve noticed that in just about every hotel stairwell you will find valves. So I’m coming out the the closet and letting you know I take a lot of images of them. They are one of those manmade subjects readily available for me as well as a subject most people will overlook. Yep, need more exercise.
