We're looking at two of America's most popular getaways on this week's Travel with Rick Steves. We'll get the latest on one of the world's hottest destinations -- Las Vegas, Nevada, where high stakes entertainment has replaced the ultra-cheap deals for which the Las Vegas Strip was famous. Rick Garman has a new guidebook to the city, and tells us how to enjoy Vegas without "losing your shirt." Then, we'll cool off in the mountains with an overview of California's Yosemite (yo-SEM-it-tee) National Park with Ann Marie Brown, who knows it inside and out, and what it offers visitors year-round. Lady Luck and Mother Nature are calling us to Las Vegas and Yosemite...on the next Travel with Rick Steves.
