The Frank Stella’s are the best. They are all over the city and they always look amazing. Two of my favorites are the Saatchi and Saatchi lobby (pictured) and the Citi Corp building in Midtown.
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...
The jetties along Rockaway Beach are one of my regular destinations when I can get out there. I grew up in a Coast Guard family and spent a fair amount of time around the ocean and surfing. I still like to get in the water and this is the first Atlantic-exposed beach on Long Island as you start to get out of the city. When it comes to the environment, constructions like these can be contentious things but they also make for a series of interesting surf spots. Its got a lot of New York metro qualities you might expect including the Subway making its stops a couple of blocks back from the water.
