The Inland Port has always been a difficult concept to understand, what with the word "port" mentioned in the same sentence as "Dallas" pretty confusing in and of itself. But the 6,000-acre land purchase by the Allen Group in southern Dallas has always represented an opportunity to bring jobs to the area, which in turn would build home values and retail opportunities and all kinds of other good things that improving neighborhoods need. The landowner just filed for bankruptcy, though, and Jim Schutze winds through a bit of the history and talks about what might happen in his Dallas Observer column this week.
