True story on the alumni networking thing...
My son worked in a nicely compensated internship program with a very large corporation last summer. He had a brace on one of his arms for an injured ligament and was frustrated because he wasn't getting much help from his doctor. One day he's helping one of the execs with a computer problem - the man asks him where he goes to college - he says ND - turns out the man is also an ND grad. Talked ND, asked about his arm, showed genuine concern and the next thing you know he has him hooked up with his son (an M.D.) who gets him in to see the best orthopedist in town for his arm thing (and it helped tremendously). Son said he enthusiastically stated if there was anything else he could ever do for him, just let him know.
Sure convinced my son that the ND support thing was real. And you can bet he'll be sure to do the same for some other ND student or grad down the road, as well.
