Some bad news/good news on the construction. It's been on hold for a while due to Indian remains being found from the digging. The good news is (from a friend on the TCN board):
"I just found out that St. Lucie County got the archeological permit to continue work on BCB parking lot, so that's a bit of good news. Hopefully they start up again soon.."
So no new date for completion but probably later than September now. We are hoping that it will be done in time for our stay there in November.
