1:08 am sunday, sounded like underhill near park, followed by car alarms. bomblike, earth-shaking thunder. anyone hear it or know what it was?

i heard this, i think. thought i was imagining it, as it woke me up. it sounded like a low rumbling on and off, to me. thought maybe it was a plane or something. no idea.

At 1:30 there were police and a total of about 10 people (some of whom may have been police) in the street on Sterling about 10 cars east of Underhill. They were poking around a car that was stopped in the street there, with the doors open. The commotion went on for a while. I've got no further info, but it was curious, and that might be where the sound came from.
