If Pittsburgh has a ground zero for human pathos, it may well be at the southeastern edge of downtown, exactly at the point where the “Jail Trail” (aka Three Rivers Heritage Trail) earns its nickname.

There, on the thick concrete supporting The Parkway east and right along the bicycle/walking path, is a stretch of wall surface where loved ones leave messages scrawled in sidewalk chalk for the inmates at the county jail.

The text is reliably heartbreaking, often written in a child’s hand, and is clearly aimed at the missing parent or family member who, incarcerated somewhere on the floors above, may or may not have one of the river-facing windows to actually see what’s been left at ground level outside. Whether or not anyone residing in the big house overhead can actually read these hand-written tributes is beside the point; here, it’s the thought that counts.

One day, we’ll do a full story on this wall as it’s got a zillion tales to tell. Until then, though, we’ve got this pair of artfully-rendered hearts, full of multicolor shading and texture, with circular connecting arrows that echo the message from BM + BM (no snickering!): always + 4EVA.

Depending on one’s relationship status and/or sentimental capacity, Valentine’s Day can be a dicey affair. But from the mass of hearts we run across all the time–red, white, pink, and yellow, spray painted on cinderblock and scrawled on dumpsters, embedded in concrete and taped to electrical boxes–it’s clear there’s a lot of love (or, at least, hoping for it) out there.

Happy Valentine’s Day, y’all!
