All maps of Q have inacuracies. That's part of the adventure/exploration that makes trips fun. If someone has the mindset that they will find AAA roadside assistance and trip-tics, that someone will be disappointed. :'(

Just like in real life, portages are lost and misplaced. What I do, is to look at all 3 maps, and try to figure out where it makes the most sense to place a portage...doesn't always work out that way.
