I'm very sorry to have missed that opportunity! It is a difficult thing, getting to know awesome people like you on LJ when it's so hard to get together in person.

Alas, the only fandom-ey thing I do annually is to attend Comic-Con at home in San Diego. Still, for all that there really isn't an HP focus unless there's a film coming out, you see an awful lot of Hogwarts students and professors!
