So, aside from the $100 I spent on gas, I ended up dropping $155 on a car battery and $16 on Friday's dinner. I guess that's not so bad given that I had free lodging and didn't pay for any other meals except $2.50 for Taco Bell on the way home. Also, the car thing could have been way worse. My old battery is under warranty still so I intend to return it.
On the plus side, my Friday dinner was provided as were breakfasts and lunches.
The conference was amazing. So glad I went. I've been a bit sick, but did a decent job of not coughing all over everyone (with the help of some Tylenol Cold...awesome stuff w/acetominophen, DM, & phenylephrine).
