Passengers walking to LaGuardia

Was scheduled to fly from New York LaGuardia to Chicago O'Hare this morning. Got there at 6:30am only to find the airport closed due to a "security problem". We sat around until 8:30, after which they started to allow people to approach the terminal building. Turns out it was due to a bomb scare. Here is a shot of people approaching the terminal building. I hope they were able to get on their flights. Mine got canceled.
