Why Mexico City does not have BattleHack? I was lucky to organize AngelHack last year and our winners also won the finals in San Francisco. Overall, we have plenty of talented hackers down the Bravo river, so I think it would be a great choice.
Theme is to hack local social problem. Space is Impact Hub. Last impact hub i organized there was creative-currency.org
This one should pretty awesome.
I have one of the axes from the leftovers in Miami and I can tell you that it's a really nice axe this year. I'm glad they dulled them down right away though so I don't slice my head again like I did last year.
