This is not my children wanting to pick the flowers, which is strongly discouraged by the park rangers, but my wife wishing to choose the photo for today. Right now the kids are in bed, but tomorrow I'll have my middle daughter try to find the two bees in the photo.
We believe these are Tall or Green-headed Coneflowers (Rudbeckia laciniata) which are growing alongside Slippery Rock Creek near the Kildoo Trail.
