Our group dwindled from 5 people to 3 for our 9 am bike tour on Saturday, March 20th because of sleepiness and chilly weather, but Paul took it in stride and got us underway with very little mishaps. This tour was billed as "Cherry Blossom tour", but, unfortunately, the trees were not quite ready to show off their flowers. Paul had done his research and knew where a couple of trees where beginning to bloom and made sure that we saw these. The tour then became a monument tour- which was wonderful on bikes in the early morning. without the crowds. We were able to stop at the Lincoln, Washington, FDR, MLK,Jr, and Jefferson monuments/memorials within our 2 hour tour. Paul was very knowledgable and had historical facts that I hadn't heard before.
If you know that it is going to be crowded, I would suggest the earlier bike tours. Overall = great experience!!
