To see a complete lunar eclipse might be worth keeping our kids up late tonight even if this isn't something directly holiday related! After all it is not every day you can see this!
Visible from the US, Central America and parts of South America, I haven't figured out yet if we'll be able to see it from where we're at, but I'm certainly going to try!!
I think I'll let my kids sleep though until I know for sure! ;)
