How common is it to receive letter from admissions asking you to apply, out of the blue?

Funny, my D got the same type of letter from Harvard which we posted on our fridge as a joke. Anyone who has read my posts knows that as a die hard alumni from Yale, that there was not chance in heck that I was going to let my child apply there. No letter from Yale. Go figure.

The novelty of the letters and e-mails wore off quickly. She kept wanting to apply to some school in Colorado because of the sweeping mountain ranges on their brochures. Mind you, this is a kid that hates camping and the outdoors.
