One of the things on my summer list this year is "watch a meteor shower". We just had one with the Leonids in early August, but it was rainy and overcast where I am, so I didn't get a chance to look for any shooting stars.
I remember one night camping with my mom, years ago, and she told me that I couldn't go to bed until we saw a shooting star. Yes, I do have the most amazing mom in the world. And yes, we did see one or two that night.
I try to get outside the ring of light that seems to grow wider every year, and experience the joy of standing under the Milky Way. It's really the only way to see where are in the universe, and maybe where we are going.

And think about where it was that you had your first or best glimpse of the amazing garland of light that surrounds our world from millions of miles away.

Maybe it will bug you to know how much you're missing every night, or maybe it will inspire you to become evangelical about preventing light pollution.
