Summer is here and the art world is going insane with activity this week. We start with Outsider Porn, which features 40 years of David Hurles' photography. Fitting for the summer is a modern version of the "Grand Tour" @ Bryce Wolkowitz Gallery. Artists from Yale University have enjoyed great success in recent years. Now you can see current MFA photo works here in the city. On Saturday, check out Brooklyn's biggest monthly art party at the Brooklyn Museum's First Saturday celebration. Stay in Brooklyn this weekend for open studios in Bushwick and in Boerum Hill at the Atlantic Ave Art Walk. On Tuesday, don't miss NYC's biggest block party (on 5th Ave), the 2010 Museum Mile Festival. Finally, Creative Time strikes again for what will be the summer's best scavenger hunt with "Key to the City," a art project that unlocks spaces and treats across the city. YES!
