i remember them when i was a kid. been here in southern cal for 45 years, & there ain't none out here. at least i never seen them. maybe in northern cal.
is your dock finished yettttttttttttt? you better hope it dosen't spook the fish away. it will probably take a few years to get them around the dock. then you can go out & dock fish. that is my favorite way to fish. may god bless you & have a great day. pw :D
