Summer weather has arrived, and people are evidently planning to make the most of it over the upcoming long weekend. A huge number of Americans are planning to hit the road over Memorial Day weekend, AAA estimated on Friday. Around 42 million people are expected to take some kind of trip, a 5 percent increase from last year's holiday weekend and the highest estimate in more than a decade. "A strong economy and growing consumer confidence are giving Americans all the motivation they need to kick off what we expect to be a busy summer travel season with a Memorial Day getaway," said Bill Sutherland, senior vice president at AAA. About 37 million will be driving to their destination, despite a recent spike in gas prices.
