Take the following as truth: Certainly, July and August can be almost unbearably hot and humid in most big cities, but some find an odd, ghostly pleasure in being in Rome on Ferragosto (on and around 15 August) when the city is abandoned to the cats and the crazy. 
Then the following statement: "Rome is almost devoid of tourists in August, but it gets crowded again in the fall." is true, false, or inconclusive?
