Drainspotting

Drainspotting? What kind of lame hobby is that? Well, according to the FAQ at drainspotting.com, “it’s fun, really. I can think of stupider things to be interested in. Hummel figurines, for example. Plus, drainspotting is free! Just walk around and pay attention to what's going on by your feet.” Okay, fun is in the eye of the beholder, I guess, but how can you deny the simple beauty of the manhole cover shown at right? Check out photos of all sorts of drains, manhole covers and similar metalwork, submit your own (although most of you would never admit to having photographed one), or comment on the ones already submitted.

Also, read why most manhole covers are round, but there are indeed other shapes that work, including triangular shaped manhole covers in Nashua, NH. (links via Off on a Tangent).
