good evening gentlemen.. I am the wife of a railfan. I need assistance. We have just moved and i can't find any of his model railroader magazines. A couple months ago there was an advertisement in the back of the magazine for a coupler that fits over the ball hitch of a truck/car. Does anyone know where i need to contact to get more info on it. It is time to shop for christmas and i need to remain the "cool" wife of all his friends. Please write me back. Thank you RRwidow!
