Since we introduced our sons to the Arboretum when they were very young, now 45 years old and 40 years old, they still go to the Arboretum often with their friends and our grandchild. The boys know the Arboretum inside and out. Everyday after school when they were young and did not want to do homework after school they knew what they wanted to do and that was load their bikes into the van and off we would go to the Arboretum. It was their time to chill out and let the excess energy of sitting in a classroom all day get tossed to the wind. And they loved it.
