We have signs posted, "Do not touch anything" around the layout. We also have Plexiglas in certain areas. However, as long as you have the young ones coming in you will have some touching and ultimately some damage. We try to make it a practice to have at least one member roaming the layout with eyes open to prevent bad things from happening. We had to cover up a red button which was master power because the curiosity became too great for the kids. Just need to keep eyes on all the time.
