Thanks. I actually only got one side of the system done this past fall but if all goes well I'll continue to expand it this year. One thing I would change is I would turn the GBs 90 degrees so the width would be 48" instead of 40". 8" isn't much but when there's 3 of them I gain 2' of floor space on the end and can still easily reach to the center of the bed for planting etc.
