I swung by the park today. It was open!
They filled in the entire park with fresh sand. I guess it's actually stone dust. It was pretty dusty there, I'm guessing after a couple rain showers (or snow falls?!) it will get better. They may not be completely done with whatever they are doing, as the picnic tables were piled into that gazebo thing, along with the agility toys.
It looks like they did try to fix some drainage problems, but we'll have to see how things look after a good rain fall.
Oh, and duke approves of the new sand. he had a blast running around like a mad man today. we couldn't stay long, but at least he got out some of his couped up energy.
