Hopped on board the metro-bus that comes to our campground and off we went for our first stab at catching the metro. We had purchased our smart-cards at the campground and then were able to load some money on to them at the metro. It was very easy to figure out how to go, especially after we asked for help from people around us. Glad to say, they were eager to help us. Gary chose the Air and Space Museum for our first visit. We were not disappointed. We watched the 3 films on the IMAX and enjoyed them all.
