Been there, too (and left 200€ for books and other material
). I saw the "Old Eagles" but I figured they'd be busy enough given the number of people around them so I left them alone. Although, I must admit that, I had toyed with the idea of letting Hajo Hermann sign my two volumes of the "Jagdgeschwader 300" chronicle (but when I overslept in the morning I abandoned that plan
).
