Ed is right. The access path/gravel road would let about 8 cars room to park and BK (Before Kayak's) I never saw a fisherman park in the parking lot. If there was no parking available you found another spot.
I forgot to mention that someone posted the owners phone number on a local paddling site with a "Call for permission" note. I think when his phone started ringing off the hook it put the icing on the cake.
I would sure like to see "Fly Fishermen Only" signs posted!
