A thousand welcomes doraboots! I am one of the hosts of the May Michfest mixer in Brooklyn. Sorry to see you won't be in town in time for the get-together, but you can find my contact info in that thread. Feel free to email me when you two get to town. I have also established a Events Happening in NYC and the Tristate, which is what we call the NY,NJ, CT greater metro area since many work in NYC and live in other states. If you are interested we can plan for an impromptu festie meetup somewhere.
If you are thinking of flying into Detroit, I would like to recommend you consider flying into Grand Rapids, MI instead and taking the Festival shuttle from the airport. The information and the timetables are here: http://www.michfest.com/tickets/shuttle.htm
