I think the low was 50 even in Central Park in August 1986 in the period I referenced in my above post, Chris. It felt like early fall, very low humidity, clear blue skies, very crisp, my first time viewing the Perseids and it was the best I ever saw them from here. The only time I saw them better was from the Poconos a few years ago, in varying colors (something you can't see in a light polluted area like we live in.) You can't even see the Milky Way in our disgustingly high level of light pollution, something you can see in the Poconos even during twilight before the sky is fully dark!
