If it seems a little crowded out there on the highways and byways, there's good reason: AAA predicts that 42.5 million Americans will be traveling this holiday via planes, trains, or automobiles, reports AP. That's up 4% from last year and the highest since the recession began in late 2007, despite higher prices on airfares (20%) and gas (16%) compared to 2010. So far, so good, generally speaking: Heavy rain on the East Coast, snow in New England, and a mudslide in the Northwest have caused snags, but nothing on a huge scale. (More holiday travel stories.)
