I also know of a college in NY with boxes. They have an area of trails where boxes have been planted.
There also at least 2 different sections of trails in SC (associated with 2 different colleges) that have a bunch of boxes available to find.

Having said this, I have to say that I am on your parent's "side". :) Letterboxing should probably not be one of the top reasons why you decide to go to any college. :)

I could MAKE my college have a lot of boxes, if you want :D

No you can't. I've been looking, and watching the gardeners. I think there's only a couple of places where a box could be placed that they wouldn't remove it, and even then, it would have to be very carefully disguised...

My sorority sister and I have started adding boxes to our college
