Cook has now visited the US Capital - Washington DC.
This was a great time to go - during the Cherry Blossom Festival. Each year, about this time, the Japanese Cherry Blossoms around the Tidal Basin in the centre of DC bloom, giving a vivid splash of colour to this area, already chock full of landmarks famous the World over.
We were lucky to see the blossoms around their peak, which doesn't last very long - maybe a couple of weeks - but it depends completely on the weather.
Cook visited the Washington Monument, the White House, the Jefferson Memorial, the FDR Memorial as well as taking a look at the Lincoln Memorial.
All these sites are situated within walking distance of the National Mall, which itself is easily accesible on the pretty decent subway (Metro),
The FDR Memorial is well worth a visit - and the Park Ranger gave a really interesting tour. Also don't miss the Korean War Memorial, which is often overshadowed by the sombre and very moving Vietnam War Memorial. Both are very close to the Lincoln Memorial at the West end of the National Mall.
