A concrete zamboni?

They’re building another huge warehouse something-or-other next to the Home Depot, and today they poured the concrete.  As we drove by earlier today we saw these guys out there zipping across the concrete on these little smoothing machines, looking like swamp rats on fan boats.  I guess these things are the concrete equivalent to the Zamboni.  I didn’t have my camera with me when we first saw them, which is unfortunate because there were about three times as many of those machines on the slab at the time.  We had to come back a few hours later to pick up the dishwasher we’d picked out earlier, and I managed to remember my camera.

You see some of the guldurndest things on construction sites.
