"They say that all good things must end, sometime… Autumn leaves must fall." And so it is with "Tuesdays with Garth." If today is a Monday, then tomorrow must be a Tuesday. But not just any Tuesday. Tomorrow is the final installment of "Tuesdays with Garth." Kind of brings a tear to your eye, wouldn't you say. But don't worry, Doc and Garth will be back together someday. (Probably on a public television fund-raising show in about 30 years.) Tune in tomorrow for one more trip down memory lane.
