I visited the Jefferson Valley Mall for the first time in a while on Saturday. I was a bit startled by the amount of unoccupied space, clearly more than could be explained by normal turnover. This was particularly noticeable in the food court, a bad sign as it suggests customer traffic in the remaining stores is also down. Maybe this is just more evidence that the economy is still not very healthy. Or perhaps the mall has started to fail. Two other enclosed malls that I used to shop at when I worked at IBM, the Dutchess Mall and the South Hills Mall , fell on hard times and slowly died.
