Terra firma and flights of fancy

Can you be married in a hot air balloon? (I just got a phone call about this - before you all rush to Central Park to get married this week, all the appointments are booked).
Can you be married in a helicopter?
Can you be married on Liberty Island? or the Staten Island ferry?

Yes -- and no. You can have the wedding ceremony all of these places - but you must SIGN the license in a specific location ON THE GROUND. NY requires a street address for the wedding location. So get out of the balloon gondola, and go over and sign the license on a park bench, with the address 72nd Street and Central Park West -- or the closest intersection. Get out of the helicopter and sign the license at the street nearest the helipad. Get off the ferry and sign the license EITHER on the Staten Island end, or the Manhattan end. Come back from Liberty island and sign the license in Battery park (near a street intersection). You'll always have your memories of saying your vows 500 feet over Central Park - and then signing the legal bits with your wobbly feet back on the ground.
