Little Rock has a great streetcar system. They are clean, nicely maintained, air conditioned and cheap. Seniors ride for fifty cents for as long as you want to sit on it. We did the whole circuit; the street market to the Clinton Library, through the Historic District, across the Arkansas River to North Little Rock and back to the market area. The driver had a microphone and gave a running commentary on the sights as we passed them. It was the best fifty cent tour we have ever had.
