After reading these posts I think I'm in the wrong line of work - Haha!
For me, the biggest thing I can think of is tickets to a University of Kentucky basketball game (Guess where I'm from...) and also I got to attend a Cincinnati Reds game. Nothing terribly exciting but I do like where I work.
My DD and I have been lucky to tag along with my DH on some work trips - not rewards but conferences in Orlando are never a bad thing

We sure got to stay in nicer resorts than we do on our own!
