When traveling to a new destination, I don't rely purely on guide books or travel sites. Instead, I ask around, quizzing local moms and dads, and finding out what they recommend. It's the all-important word of mouth straight from my peers. I've dined at the best steak house in Brooklyn, played in the coolest park in Los Angeles and had the best tacos ever in San Diego—all due to helpful tips from friends who live in these cities. If you're headed to San Francisco, Los Angeles, New York, Miami, Chicago, Philadelphia, Atlanta, Boston, Dallas, Houston or Washington, D.C., we have that all-important word of mouth for you (in this case, emails), straight from some of the best bloggers in each locale. Happy travels!
