So, it turns out that it wasn't just me. The Gamma Delphinids really were a no-show. Earth's orbital path realigned with what it was back in 1930 when the Gamma Delphinids were first seen, and some scientists thought that this would mean that the planet would once again pass through the debris field of some unknown comet. It was a long shot at best, so it's not very surprising that nothing happened, but it's still a little disappointing.
Oh well, I still got to spend a good portion of time enjoying the wonder and majesty of the universe under the night sky.
