When cities come together

This is for me is not only wonderful but is remarkably so.

What more can you want of cities but to meet and to share critical data and info re:
1. what their problems are
2. how some might have faced them and solved them
3. what difficulties some have in solving their problem
4. what good ideas might they have tried with which to share with each other
5. what hopeless ideas that they have tried and found that they really did not work
6. discovery by others who are just about to try out these same ideas that others found just did not work
7. sharing what ideas failed at first but by some innovative  tweaking here and there, it did help to solve the problem.
8. etc.

This is the extra-ordinary merit for the call of this meeting.
