I so appreciate all of the information. I'm going to have to come back to this tonight when I have more time and really digest it. To quickly answer one of the questions, I am in a suburb north of Houston (Humble/Kingwood if you're familiar with the area).
And I didn't realize that so many other GT kids were into greek mythology! Dh had a conversation with him about it a couple of weeks ago and came to me later saying "Do you realize just how much he knows and understands about mythology??" I'll have to share this commonality with DH!
