There are 5 flags to be raised on the roof of WL. At 8am, one family gets to go up to the rooftop with a flag guide who will explain the flags and let you raise them up. The you get some time to take pictures up there and you get to go where most people don't get to go to.
At the end, you are given a certificate stating that on that date you were honored as flag family.
It's really cool and if you have kids, don't tell them and let it be a suprise! They'll get a kick out of being able to go up on the roof!
