Not sure if I will head up there Sunday or not. I would like to fish the pier and take some fresh pictures but as I said on the phone it might be better to do it as a loop. I need to revisit Boonville and I could do a short trip hitting this pier, Lawson's Landing, the piers in Bodega Bay, and then drive up to Point Arena before heading over the hill to Anderson Valley and seeing some old friends. Then head back down south on HY 101. The fall, when the lings come close inshore, is a good time to visit the pier at Point Arena.
As for Nick's Cove, I imagine the fishing isn't too different from the fishing that took place on the original pier. — a shallow water fishery over mud, in fact pretty much mud-flat like at low tide. Bat rays and leopards should be available when the water is right as well as jacksmelt, several perch, and some flatfish. Pretty much the normal stuff but it would be good to see what it produces.
