I also managed to run my car battery flat; I'd been powering my CPAP machine via an inverter off the cigarette lighter both Friday and Saturday nights, and didn't run the car on Saturday to recharge after Friday night. Good thing I keep a set of jumper cables in the car.
Despite those frustrations, however, it was a good time. The Friday night sky in particular was wonderfully clear, and we could easily see the Milky Way (a frustratingly rare sight in the Boston suburbs). Saturday was just about perfect - warm, low humidity, and sunny for most of the day. The traditional Saturday evening cookout was its usual success, even if we did run low on hamburger buns and had to substitute hot-dog rolls.
And I managed to get all packed up before the first thunderstorms rolled in Sunday morning ...
