Train horns and Hummers were mentioned in the same WSJ article recently.
It's here.
Best quote from the article: "For the past few months, Jose Lopez de Zaldo of South Beach has been periodically awoken in the wee hours of the morning by what he thought sounded like trains. 'I was very perplexed,' says Mr. de Zaldo. 'I've been living in Miami Beach for 15 years and never heard train horns.'"
