In the Solomonic tradition, Dallas and Fort Worth split their differences and built their massive international air hub in the no-man's-land between the two cities. Dallas/Fort Worth International Airport is equally close to each of the region's two economic hubs, but so far away from each that it's a pain to get there. Getting to DFW Airport is still a chore, but, thanks to DART's extension of its Orange Line, it's a little easier and now much cheaper. For a $2.50 one-way ticket, you can ride from Plano's Parker Road station to DFW by light rail train. Stops in between include Arapaho, Park Lane, Mockingbird Station and the Arts District. OK, it takes 92 minutes. But you don't have to sit in traffic. Take something to read.
