I think this is super cool and useful so I’ve put the map in its own separate post (here) for maximum visibility:
+Ferrell Riley has provided a map for all G-Hangouts peeps to pin themselves to. Allowing people to know what players are in your timezones
Kudos to +Johannes Oppermann as the ideas man!
(you don’t have to put your exact address but town or region will do)
Might be of help, should be open accessible
