With a security guard critically injured in a gatecrashing trampling incident and an attendee being found dead in a parked car, Miami Mayor Tomas Regalado and City Commissioner Marc Sarnoff have been steadfast in their determination that the city no longer host the massive event, which brings in tens of thousands of dance music tourists and millions of dollars to the surrounding area.

Sarnoff continues to turn up the heat, recently compiling a "worst of Ultra" video culled from footage found on YouTube. Among the images on the video include gatecrashing fans, a violent fight that goes unchecked, and a shot that may or may not show a woman urinating onto the head of a passed-out man that went viral soon after this year's festival. "The money that Ultra is spending is nothing more than blood money," Sarnoff told CBS Miami this week.

In reaction to the city officials' opposition to the festival, Ultra promoters have launched a Change.org petition to "Keep Ultra Music Festival in Miami."

"Recently, certain City of Miami officials have called for an end to Ultra Music Festival at its current home of Bayfront Park in downtown Miami," reads the petition. "In order to stay at Bayfront Park we need your support now�Please sign this petition to indicate your support of Ultra Music Festival as a catalyst for economic activity and key promoter of the City of Miami's reputation as a top entertainment and leisure destination."

At press time, the petition had already generated more than 20,000 signatures, with almost 30,000 more necessary to reach the goal of 50,000 signatures.

Support for the petition has come in from all corners of the dance music community, including such marquee artists as Tiesto and Danny Avila, local clubs like LV Miami and industry insiders such as publicist Alexandra Greenberg. Festival supporters have bombarded Twitter with the hashtag #SaveUltra.
