New York City easily won as the local for the "all US fibs get together". If you compare the Americans to say the Germans, you see a big difference in community. They are more civil. They meet every year in the summer for the party etc. The US get together has never got from what woody allen says in a movie, "i have an idea and if i get a little money i will turn it into a concept".
So we have the local New York city similar to the dalai lama who said to the hot dog vendor, "make me one with everything". Further, considering how dirt cheap the US is for europeans (talk to inim about this) euro fibsters might be tempted to come to new york. Also, in the spring transatlantic flights are supposedly going to be cheaper.
Therefore, all we need now is someone from the New York area to host. Not physically host but organize, boots on the ground.
Anyone who lives in the New York area is welcome to designate themselves host.
