River Rat Jim's

At 1112 East Patterson Street, is a house that sits on the river. I have passed by it for years. The sign on the place calls it River Rat Jim's. I wonder if there is a connection to the River Rats I wrote about before? The the original River Rat Clubhouse was located at "a little house in the rear of the home of Mr. And Mrs. J. F. Griffin, 1109 Patterson St." and that house is caty-corner across from this house.
