meh...there is an at least barely profitable trade route between any station and any other station...mostly...
so, discovery doesn't mean much...
i like to discover the best route to RP...(that means get pirated, fight pirates, get caught carrying contraband, not drop it, get killed by the RM....argue with bushido about who better portrays the GC...etc)
discovering trade routes isn't really worth it...discovering the fun is.
oh, and i like taking stuff(that i cant spell) from Pittsburg to LD-14
