Book excerpt: Completely revised and updated, Let's Go: USA is the perfect travel companion for the fifty states and Canada. This edition, grounded in Let's Go's forty-five years of travel savvy, features more comprehensive information on modern America and expanded opportunities to extend your travels through work, study, and volunteering. While detailed maps, listings, and practical advice make America's largest cities accessible, a new "Out of the Way" feature takes travelers to cool sights and experiences off the tourist track. So whether you'd rather taste doughnuts hot off the assembly line at the birthplace of Krispy Kreme or spot George Washington's initials on a 100-million-year-old natural bridge, Let's Go gives you the latest on how to get there, get around, and get busy.
