Higher gas prices will keep more Floridans home during the Fourth of July weekend that begins June 30, according to AAA. An estimated 1.9 million will travel at least 50 miles from home, down 2.7 percent from a year ago. Most — about 1.7 million — will drive, which is 3 percent less than last year. The drop off isn't surprising when you consider that gas prices are about $1 per gallon higher than they were a year ago. But AAA projects more than 154,000 Floridians will fly, a 21 percent increase. Nationwide, the average Fourth of July weekend trip is expected to be shorter: 573 miles, compared with 617 miles last year. But typical travelers will spend $807, up 25 percent from a year ago.
