As a child, I was frequently on trips with my family to the Appalachian mountains, and that was the one place where I'd then seen Rhododendrons, which grow in abundance there. But we went on very few hiking trails, and what hiking we did do was very short, because my father had a bad knee. So most of our observatins were from or near roads, and all rhododendrons that I clearly saw were along or near roads. So I thought that was the only place they grew, and that the "rhod-" part of their name came from their occurrence alongside roads.
