No. I haven't seen it. It's not visible from the freeway. That's where I've stopped. This is actually a longer area that runs along the river/creek and river walk. I'm guessing the sign is on the other side of the wooded area and across the water. I haven't had occassion to be on that side.
It would be great if you could check where this is supposed to be.
There is now supposed to be a sign asking for donations according to WND.
