One disaster: my checkbook is missing. I had it out just before I left town on Thursday (I had to write a check for cash because I unexpectedly discovered my ATM card had expired). When I got to the con, it was not in my briefcase, but I didn't panic because I assumed it was sitting in my car. (We took my mom's car because mine, while drivable post-accident, shouldn't be driven long distances.) But when I got home, it was not where I expected it to be.
Now, I'm panicking.
