I have to give my credits to the TAR production team, Season 18 and 19 we got the full route a day after they had been there ( with is a great job, from a lot of the people here).
In Season 20 they got track down to leg 4 in Turin, then the where off the radar to leg 11 in Japan.
So they are getting better to travel unnoticed!!!!!!
Witch i think is sad, because i love to read the timeline with all the legs, because of all the hard work some people have done!!!!!!!!!!!!!!!!
