There are human footprints, shoe prints, bicycle tire tracks, and lifeguard truck tracks; there are gull tracks, godwit tracks, curlew tracks, and sandpiper tracks.
And then there are these mysterious faint linear tracks, and we finally saw one being made — by a bee. Or, at least, something that looks like a bee: large and winged and multi-colored and rather bee-like. This bee-creature was upside-down (!) in rather wet packed sand, near the surf line. Amazing maze of faint jagged lines, the traces we leave.
