It like it when Adobe provides me free fonts. I hate it when they install them in strange places and you can't seem to find where that strange font that you never ever use resides. Or where that triple version of Courier is hidden ? Well, look no further:
Library/Application Support/Adobe/Fonts --> this one is obvious !!
But they can also reside in:
Library/Application Support/Adobe/PDFL/6.0/Fonts
