We didn't get *that* far into it.

Yet.

His Lordship wants to be an astronomer when he grows up (which by his reckoning
will be next year) so we've been reading books, visiting planetariums, taking
in the night sky, etc. While we live in Arlington, VA where there's a lot of
light pollution so far we've manage to squeak in the
Mars-Venus-Mercury-in-a-single-sky thingie, phases of the moon, etc.

We don't have the time to catch the Perseieds this month but I'm hoping to
convince a buddy and his kids that a rural camping trip in November is the
perfect opportunity to catch the Leonids. I caught them about two years ago
during a peak and the experience was unforgettable.

Best,

Marc
