If you live and work in the area, or plan to fly into DFW Airport or Love Field to attend the TCCTA annual convention in downtown Dallas, you might be interested in convenient transport via the Dallas Area Rapid Transit system (DART).
There are stops on several rail lines (organized by color), mere steps away from the convention headquarters hotel, the Sheraton Dallas. See the links below.
Fares are reasonable and will eliminate parking fees, rental car expenses, or taxi fare.
If you plan to fly, please have a look at this online graphic provided by the Sheraton. You will want the Orange Line from either airport. (Traveling as light as possible might be a good idea, too, depending upon the crowds.)
For those who live or work in the area, here is the general DART link. You can access maps, schedules, fares, and other useful information.
Here is the TCCTA Convention site, which includes the latest hotel updates, details about programs, and a chronological list of events.
