Walked around Havana in the heat. Rob gave a tour of the architecture and history of Cuba. Got scammed once (Local being very friendly and takingy you into cafe to ask for pen and paper to write down directions to a festival, ordering mojetos and leaving you with the bill) - second time refused the drink and bill annoying both the local and the bar man. The first scammed did helpfully tell us that Cuba has two currencies (local and tourist). Everything for the tourists is very expensive. Changed some money to the local currency to buy cheaper food.
