Rogues Gallery unclimbed lines?

[tobyfk]

I have been spending some time at Rogues lately and have been struck by the amount of unclimbed rock, even near the easily-accessible established routes. There are even a few lines that are quite clean but unbolted ... is this because some deranged hero has done them trad but they have then been left out of the guidebook? An obvious example: the line right of Cancelled Czech?

I wondered the same thing. The steep crag left of the Tommy Gun wall also has some obvious unbolted lines.
