Have any of you been there? I just learned about this when I rode bike this morning for my own commute. I was surprised to see many bikes and pedestrians on Park Ave which was closed to motor vehicles. I thought it would be nice to ride home this way again this evening, but was disappointed to know it's only 7am-1pm! It should be at least for one whole day, and I wish it's for both Saturday and Sunday. Of course would be nice if it's for the entire summer weekends.
