Hey [PRESIDENT],

I was just thinking about all the great times I had working at
[NAME].  Boy, those sure were fun times, no?  I mean, who could ask
for more than working in beautiful downtown [CITY]?  (When did
[NAME] move to [STATE], anyway?).

Well, after leaving my buddies ([BOARD]), I decided to go back to
school.  I'm now at Rensselaer.  Rensselaer Polytechnic Institute is a
college in Troy, NY, only a few miles from [CITY].

Just wanted to drop you a line, [PRESIDENT].
Take care,
John Smith.
