In a pretty bold move, Mad Decent's 2012 Mad Decent Block Party was held in five different cities (Toronto, Philadelphia, New York, Los Angeles, and Chicago). Their 2013 teaser video didn't reveal much, but we heard this year's edition would be bigger than 2012, and over the last few weeks, the Mad Decent Block Party's Facebook page has been dropping hints to the different cities that will be hosting Block Parties. We see Philadelphia, Toronto, and what looks to be Baltimore and Miami represented. Can you decipher which cities might/could/should be hosting Block Parties this year, before Monday's big announcement?
