[x-posted in several fora]
There is a Google map for players of this game that dates back quite a while—I'm afraid I don't know the originator to give them credit! It hasn't seen much love in recent times, though, so I thought I'd give it a little shout-out, and a kick.
Because I thought it'd be a shame to lose the work that's already been put into it, but also would like to have it more up-to-date… I made a new layer on the map called "Current as of 3/2019", that makes pins green to stand out from the old data.
If you, too, are into the idea of making the map more up-to-date, please add yourself to this layer. (I had to use a desktop computer, as well as delete my old pin and make a new one.)
