Bruno Gambarotta and his grandchild Carlo Edoardo are the special correspondents of a long walk along the Po river. From the bridges to the old laundries, from the wonderful artistic places to the sports and the recreational activities, from the quarry to to the naturalistic museum, from the gold diggers to the stork oasis. Every stop is a precious occasion to look at, remember and set off the Po river, its environment and its history.
