T1, T3 but where is the T2 (Monday 2nd February)

Went the total tourist circuit today using the tour buses. For 5CUC (Cuban Convertible Pesos) or about $5US you can buy an all day pass on three bus lines the T1, T2 and T3. We were able to find the T1 and T3 but could not find the embarkation point for the T2. Nevertheless we saw a lot of the town and discovered many new building and sights. Unfortunately, we did get stuck on the upper level of one of the buses for about an hour as we were locked in when the driver went to lunch (don’t ask – it’s a long story and we were not the only ones). Finding food in Havana is very difficult and this is attested by an old Cuban joke which goes –
Question - What are the three major failings of the revolution?
Answer - Breakfast, lunch and dinner.
Things are very expensive in Cuba and much is in short supply. However, there is always something that you can get so it is not a total loss and tnhe food is generally fresh and delicious.
