I'm making a trip down to New Jersey around Saturday, September 12, and was thinking of including a sidetrip (or two) to either Ricketts Glen (PA) or Watkins Glen State Park (NY), or both. Of course, I'm primarily interested in shooting the waterfalls. I'm wondering whether or not those dates (immediately before or after Sept 12) are good with regard to waterflow and/or even fall colors, or whether its too early? Anyone have any thoughts on this? Thanks.
