This morning, drive deeper into the Black Forest, then stop for 
a WOODCARVING DEMONSTRATION, followed by a delicious piece of Black Forest Cake. Arrive in Heidelberg, Germany’s oldest university town, of Student Prince fame. Time to stroll around in the Old Town, then ride the FUNICULAR up the hill and visit the red-walled CASTLE where the GREAT VAT, a 58,000-gallon 18th-century wine cask, attracts particular attention. Return to Frankfurt, where a special farewell dinner with wine awaits you at a local restaurant to say, “Auf Wiedersehen!” (Breakfast, Dinner)
