I know "nature preserve" is in it's name, but the county's park website lists it as a park and describes it as a park. I believe it was in the family's stipulations when they donated land to county that it be called a nature preserve, but I don't think it really is.  I believe leisure tag should be park instead of nature reserve.  https://www.mycountyparks.com/County/Story/Park/Hertz-Family-Woods-and-Nature-Preserve.aspx
