I want to do a HO set for my son, but I don't have much room to put it. It will have to be something I could move or put away easily that's why I will most likely go with styrofoam or something similar for my board. I was thinking about a 4 X 5 or 4 X 6 for the size. My question is will I be able to make an "ok" track layout rather than just a boring circle? Nothing too complicated just not too simple. Thanks!
