Megan, I am so happy you decided to join us in the Eat Local Challenge ! It's a lot of fun and somewhat sobering , especially when you realize how much of our food either 1. comes from incredibly far away or 2. is packed or distributed by some far away place and you have no clue where it comes from or even what is in it !
As far as fruit which is ripe right now - apples, peaches, blackberries, raspberries, plums, pears , melons of every description. I'm sure there are a few more, but the above should be readily available everywhere.
Can't wait to read about what's cooking in NYC !
