Unfortunately, I had to leave the convention early Friday morning to attend a family function. In my haste and because of the early hour, I left my carry-on bag in the taxi at the airport. It was a black canvas briefcase type bag. It contained my cell phone (I have suspended service---it was unused as of Saturday afternoon.), my appointment/address book, and some other items of little value. I have called every taxi company in Las Vegas with no success. Any suggestions?
