the epic journey that began on the streets of bologna , on foot , then a cab , then a bus to modena , a taxi all the way to milan , more little hikes , more cabs , then the train destined for stuttgart , but with an unexpected detour in zug , where another driver took the cash and hauled him into zurich , two streetcars , then franz and the green bmw doing 150 kilometers all the way to munich , where the warm and welcome arms of lufthansa brought him home .
