Let me see...
Hmmm....
Local Guides use Google Maps and supply information in the form of Photos, Corrections, Reviews, Answers... et al
Meet-ups have a Geographical Location as well as a Specific TIme.
So when I go look for meetups, I get the latest meetups from wherever (places not even close to me - I'm in NYC and don't have plans to go to Cairo any time soon).
These Meetups are listed on a date basis, from today forward.
When I select New York (type it into the Cities field) I see nothing - likely that there are none.
But why not have a MAP Selection, showing a world map, where you can zoom in to narrow search by Geographic area?
And further have a date selection (filter?) if there are alot of selections in the area?
