My own desire is to avoid duplicates for any one season and download the rest to use with Google Earth/Google Earth Pro. I could never be sure which files to download. At a minimum it might be useful to edit the OP to include the links to the specific posts that have the most current files for particular seasons, that for me would work as well until there is a comprehensive file for the US and for the regional editions.
I do know we have an earlier compilation (and I helped place the season three start point in the Everglades, which was insane because the area had been developed greatly between 2002 and 2012 when we were searching. I at least had managed at TARcon 3 to confirm the area of that start with Drew Riker, since we, as having been former residents of Miami could refer to the area the way the locals did. I'm preety sure I still have the old kmz file on the other notebook, but I may post it if I can find it and if it would be of any value. I also recall trying to help to locate a pit stop in northern Thailand in a rural hamlet that was extremely hard to find.
