The Historical Tour via Washington DC (Part II)

If you're still looking for something even more unusual, visit the USS Slater, a museum ship in the Hudson River. 

Time to try the original Buffalo Chicken Wings at Anchor Bar. Don't forget to visit the nearby Niagara Falls.

There is an amazing collection of modern and contemporary art in the Albright–Knox Art Gallery.

Get to see the only remaining US World War II fleet submarine at the USS Cod Submarine Memorial. Go boating or have a nice picnic at the Rocky River Reserve.

Experience a Costa Rican rainforest in the Cleveland Botanical Garden.

The Phipps Conservatory is one of the world's greenest public gardens and home to Café Phipps, a 3-star Green Restaurant Certified eating establishment. Find fossils and dinosaurs at the Carnegie Museum of Natural History.

It would be impossible to visit Washington DC without taking time to visit the Washington Monument. The African American Civil War Museum is also directly across the memorial and is a great place to learn about the men who fought for the Union in the US Civil War.
