Hello, long time lurker. I grew up a lego fan and got out of it for many years. My son is now 6 and we've begun building mostly star wars legos together. I have been into O gauge trains my entire life, and recently taken my layout down and begun building a lego layout to enjoy with my kids. The kids have really enjoyed it since they can handle the trains much more than the O gauge stuff. I built a 10.5'x9.5' L shaped layout and we're having a blast with it.
