In less than two weeks, Coloradans will catch trains, planes, buses and cruise ships for the Memorial Day holiday. But by far, the most common mode of travel will be in their own vehicles or rentals, whether that be by motorcycle, car or recreational vehicle, according to a projection released Wednesday by AAA Colorado. All together about 785,000 Coloradans will head out for an extended weekend vacation, with 690,000 traveling in their own vehicles, AAA Colorado said.
