Chris’ sister Nancy, Abril and Mia came to visit at the end of July. The National Model Railroad show was at Cobo Hall in Detroit. We spent a few hours looking at the spectacular models. LEGO model builders were also part of this show.Chris’ sister Nancy, Abril and Mia came to visit at the end of July. The National Model Railroad show was at Cobo Hall in Detroit.
