There was an issue of Ghost Rider during the Dan Ketch era, Howard Mackie was the writer..Salvador LaRocca was the artist...I just don't remember which issue it was... There was a guy who came to Dan's door...he was an older man...same color hair as Dan..I believe he had a goat-T...in a very "Mackiesque" sort of way..we were introduced to this guy...who smiled ominously and claimed that he knew him very well. Typically..we never hear from this character again. I don't remember the issue and don't feel like going through all those issues again...but who was that mysterious guy? Was he the reference used to "Mister Eleven?" or was he Dan's Father? Who was he? I know I'm not going crazy when I tell you I remember seeing that panel.
