Another Mile Marker. My second. I've got something in me telling me to seek out and shoot as many of these roadside shrines as I can find, and put them all together in a themed presentation of some sort.
Aren't they sad things to behold, those "mile markers", as you call them? I could contribute to your collection, we've got plenty of those on the sides of our roads here in Germany, too

...
Indeed. They are sad, and there's a lot of story here, at each one. Obviously, these are spots where something dramatic and tragic happened that resulted in the ending of a life, but that story just scratches the surface to the passing motorist.
So now I pull over, I get out, and look closer, and I can see that someone still comes here to upkeep the spot, to refresh it with decorations that celebrate and honor the life that ended here. But I still know nothing about the person, not even a name, nor any details about what exactly actually unfolded on this spot. They are silent on that score, nameless, storyless.
Today, it is quiet, peaceful, save the occasional car going by. Its occupants barely notice the drama, the love, the care, that this shrine represents. So I will document it, with the road in the frame to show it as the familiar thing we've all seen and passed so many times in our travels, and try to do so in a way that makes a few stop to think about it when they see my photos.
"Mile Markers" is just one of the naming ideas I have for the series. I haven't actually settled on a name yet. I'm trying to think up something clever, but dignified, not macabre or disrespectful.
