The dog days of summer are upon us! So many things to do and so little time, so park nearby and help yourself to a cache and dash, and get back out of the heat!
The Dog Days originally were the days when Sirius rose just before or at the same time as sunrise (heliacal rising), which is no longer true, owing to precession of the equinoxes. The Romans sacrificed a red dog in April to appease the rage of Sirius, believing that the star was the cause of the hot, sultry weather.
Dog Days were popularly believed to be an evil time "the Sea boiled, the Wine turned sour, Dogs grew mad, and all other creatures became languid; causing to man, among other diseases, burning fevers, hysterics, and phrensies."
So stay cool, find some caches, and enjoy the dog days of summer!
