Imagine thundering hooves and creaking stagecoaches as you amble around Historic Heritage Square, a cluster of stately Victorians. To view the interior of one of the homes, join a tour of the 1895 Rosson House. For more modern distractions, beeline to the Arizona Science Center, a high-tech, interactive temple of discovery where kids can slide through a stomach or lie on bed of nails before winding down at the five-story IMAX theater or the planetarium.
