Being on this site for a few years, I've seen a lot of knuckle heads that just cannot form information given in a helpful, constructive way. All it appears that they want to do is show the questioner how much they don;t know.
If I remember right, Lance did not have his father around to guide him at what he attempted to do, BUT the kid was at least wanting to learn, and was inventive and inquisitive.
I don't post much, but some with high handed retorts and sarcastic replies really get me ticked.
