I don't think we have to get on our high horses here. It's a hypothetical question, and it's OK to have an opinion after all. Isn't it? It was where I grew up, anyway. I don't think we have to get into a "best" this or "best" that, either. It's MY personal Rushmore, and feel free to may YOURS different. "You can be in my dream if I can be in yours."

Without further adieu: Woody Guthrie, Pete Seeger, Ralph Stanley, and the mighty Bob Dylan.
