Where are they all going?

I admit, sometimes I have insomnia. So, what can I say? When it happens I read, or watch television (there's some horribly silly stuff on in the middle of the night!) or I write. So, I fill the hours, although I'd rather be sleeping.

This morning, it was maybe 4 am or so, I heard traffic in the distance. Mind you, I live on a long, quiet stretch of road, and it's usually deserted at 4 am. But this morning I heard car engines, and they came steadily closer. I peeked out the window and eventually they passed right by my house...five cars. Not speeding, or driving erratically. Just driving, one after the other.

Now where do you think they were all going?

It's been bugging me for hours. If you know, please share with me. Because really, now that I'm sleep deprived, who knows how much longer it's going to bug me? My guess is, all damn day.
