If you hiked along the park road over the main dam at East Fork, then you could not miss the wing dam, as you cross it along the same road shortly after passing the visitor center.
I was hiking in the opposite direction, Visitor center being my finishing point. I never made it to the park road, because I took a wrong turn on one of the horse trails on the short off road segment.
My point is,I really want to get out there and paint some blazes, but I need someone who knows where we are allowed to blaze and where we are not, to help me out.
