The falls section of cardiac canyon. Did it back in the early 80's with a bud from Tokeland. Took a 15 fathom shot of half inch poly and iron balls to pull that one off in a 16 foot Lavaro knock-off built at Westport shipyard. Good thing we borrowed the boat for the day as I was bailing steady by the time we hit tidewater wouln't want to take my boat thru that.Anybody out there know where I'm talking about?
