Thanks EXT2Rob, I didn't even think about barriers! Do you think hay bails would work the same? I've got access to those easily. I'm hoping to entice some people around me to pick up the hobby once the track is built, but for know it's just me. But I think I will go ahead and build it 8' wide in hopes that more will join. Like the famous movie line goes "if you build it, they will come" lol
