Blue Moon

The Blue Moon through the oak tree outside our window is beautiful. I hear tell that sometimes a Blue Moon is actually blue, but I've never seen it that color.

There is a popular idea that the Blue Moon is the 2nd full moon in any month which has 2 full moons, but Sky&Telescope debunks that notion, as does about.com's urbanlegends site.

When the kids were little we had a book named Walk When the Moon is Full. Well, we still have it, but we don't still make the walks; I've forgotten when we stopped those. We would take a walk on the night of the full moon and notice what differences there were from month to month. One of the early walks was when my oldest was just 3 or so, and there was snow deep enough to make snow angels in the moonlight.
