With the International Dendrology Society, I visited the Arboretum in Fall 2009. As we arrived in our bus, we prepared to get out but were told we had to travel on to an appointed debarkation spot. I can assure you that it is true TORTURE for a dendrologist to be driven through the Arnold Arboretum and not allowed to stop!!! (Of course we did have a wonderful visit once we were allowed off the bus!)
