How badly could it hurt. It is after all the longest day of the year. I think it is a great exercise and challenge. So it is settled, Mergirl will be open that Sat. June 21st, but it will be dark. Bring your checkbook because the credit card machine won't be working. This is going to be fun.
One of his other wishes is to get The Empire State Building to be Dark until Midnight that night as well. Write them, call them and email them to encourage the almighty powers that be, to keep the lights off at least until midnight.
