It doesn't seem that long ago that I camped out all night at a local area church in the hopes of getting my twins into a good preschool program (actually 14 years ago). I remember how desolate I was when one twin made the number cutoff, but the other got put on a waiting list.
I then had a choice. Wait and see if the other twin moved up to a spot in the program, but risk having nowhere for them to go if that didn't happen, or start looking all over...
