I have to add my two bits since I go in to visit my Brooklyn grandchildren a couple times a year. If you like gardens, the Brooklyn Botanic Gardens are wonderful. Mid May is when the bluebells should be blooming in big masses. I also loved the new garden area in Manhatten that has been developed over the last few years. It is called the Highline Park - it is a long narrow park built on what used to be an elevated freight train track. It's a wonderful walk and it's fairly narrow, and filled with native and naturally occuring plants to the area. There are wonderful bird houses, and benches for people, and water features --it's just a really nifty place to take a walk and end with a wonderful cup of coffee and pastry at the end! Wherever you go - enjoy this wonderful city!!
