Many parents take their kids to play at the depot plaza every day. Very often the kids end-up playing and chasing each other in the redwood tree grove at the south-western end of the plaza (right by the gravity car). I have seen kids sometime bolt out of that grove onto the street to escape a chasing buddy. It's just a matter of time until an kid will be hit by a car. Building a fence on the side of the grove that borders the streets would take care of that problem. Kids can still play there. It's cheap and it will let both car drivers and parents feel more at ease.
