The first was an image challenge.
The 2nd is a map-based challenge. It's just been launched on Twitter.
Where in the world have you been to?
Your second challenge is to make a map using the Big Huge Labs Map Maker, which is a resource that I've used many times for many years, and which is part of a bigger suite of tools which you may find useful....
The maps that have been created are also embeddable as below...
Make yours @ BigHugeLabs.com
If you manage to make one please share with the hashtag #challenGEO2
Thanks to those colleagues who have already responded via Twitter.
Which part of the world haven’t you visited, and which would you like to visit?
