I took my little guy to the Friar Mt Model train layout in Sparta NJ. 20 minute drive from my house. Its not a hudge G scale layout but fun to watch the trains when cabin fever starts to settle in or you need to kill some time. All the buildings were scratch built and there are a lot of them. Here is a short video I made. The squeaky voice in the background is my little guy.
