I couldn't find any info on it but I think Worcester still has a mortgage on the DCU which opened in 1982. The Worcester Center Galleria (mall) was profitable for only about a decade after which it steadily declined and was eventually demolished. It never paid for itself. Polar Park was another roll of the dice and only time will tell. I think all of these things were attempts to restore Worcester's economy after industry died there. Hopefully Polar Park will draw other businesses to the area.
