Great choice! I'm sure you've read the story of filthy 14 but if not look for it at BCM's site. (A reprint should come in the box, too.) I think you're the first on this forum with an EAG so we'll love to see pictures. And as mjkeat said you'll have a coupon for EAG training ($200 I think) so watch for a class near you this year.
I'm curious, being in NY what compliance issues will you have with the EAG?
