I can't be sure about this; but, I believe the only videos on model railroading that I have ever seen that hasn't been messed up by distracting noises voices; or, a head popping ups along side the layout, has been done by Pelle Soeborg. I guess I can't figure out why model railroaders allow this to happen. I love to see videos of other people layouts! However it is rare to see them without giants being sighted along the right of way; or, being able to hear them talk. Maybe this doesn't bother others, don't know!
