Water droplets on a door latch of my Timpte refrigerated semi-trailer caught my eye on a recent damp morning, so I tweaked the color a bit to give it more interest. If you are wondering why I own a semi-trailer, it is my store room where over half the stuff from my former mobile home is still in storage. In the trucking business, these are known as reefers, but there is nothing illegal or narcotic about this kind of reefer.
