Natural/fast speed please!
If you're up for an adventure, check out Governor's Island. Fairly unknown yet fun and happening, it's an up-and-coming attraction for many reasons. This 172-acre island is a former military base, sold in 2003 to the people of New York. There are many ongoing exhibits and events featured on the Island and the best part about it -- it's all free. Only a short ferry ride away, it definitely a must-see.
