Rally for Kids With Cancer, a fundraising event that has taken place in other cities such as L.A., rolls into Miami this weekend with the Scavenger Cup, with Eva Longoria hosting and Marini as one of the celebrity navigators.

"I came here with $400 and a tourist visa. I said, 'well, if anything goes wrong, I can sleep on the beach.'"

"I have to buy a place here," he said of the Magic City. "I feel happy here."
