This is a great park, from free concerts to summer to the Brooklyn flea markets over the weekend or take the ferry across the river. Rain or shine I never get sick of that view.
This is the new bike share program of NYC. It's amazing. I went for the 1 year membership for $95. You can also get day passed for around $10. There are stations all over the city. You can now have a wonderful day changing between walking, biking and the subway. Finally, I can stay away from the crazy cab drivers...
