Kriston:
Honestly, just by telling them what you tell us around here, I reckon you're fine. I'm astonished at your little guy and the things he comes out with.
When filling out Benjy's YSP application, I included several anecdotes that really describe my ds's thinking and exemplify what he's able to do. We don't homeschool and he's not as overtly intellectual as many of the kids on this board, so it was difficult to answer the questions for me, too. But I did it ... It is hard, though!
You're right; I'm not used to having to hold my breath on something academic for him. On the flip side, even if he gets turned down from Davidson ... well, to be able to apply at all is not too shabby, is it?

I've got to agree: If you're getting too involved, just mail it. And include some of the things that your ds says, because he sounds mind-bogglingly brilliant to me.
