We are the pioneers of near bubble, completely uninteresting exploration!I am still finding partially explored and the occasional completely unexplored systems around 1,000ly from the bubble, the problem is most people aim at the pretties, and follow the same path thousands of CMDR's have done before them.
Edit; In fact I have just jumped into a completely unexplored system exactly 1,189ly from Sol, so there's still stuff close to the bubble to find.
