Another idea with respect to launches, their parking allowances and possible adjacent parking would be a thread in this forum that included a continuously updated kml file.
this file would have specific launch locations and any additional notes or locations that would be of interest plus any related comments too.
The updates could come from posts to that forum thread or possibly by each poster – as files are so small, if the ‘most recent’ one was corrupted, it would be no problem to just load up the previous one and move on from there. And for backup, an older but perfect version could be held by a nominated person.
All that would be required would be the ability to upload a file of some kind [a kml or probably a zip file] to one’s post.
anyway, another idea.
