I found it pretty hard to answer all my friends questions about what my favourite thing was in New York. There's not really one thing. It's not really just one sight.
Before we went to NY, I decided not to take a tourist guide with me. Instead I purchased
New York City Notebook by Moleskine (It's if filled with handy maps and empty pages so you can write your own guide) and browsed the sites of some of my favourite bloggers for tips. The result was a great week where we experienced a NY we would have never experienced otherwise.
I used to cherish my lonely planets, but there is no better tour guide than people who love and know their city. So hurray for New Yorkers and Moleskine who made our NY trip all the more special.
