I was a passenger in a cab driven by William Brown, hometown of Vassar MI. The cab picked us at hotel at north end of the strip, in a rush to get to the airport, managed to leave behind my cell phone in his cab. Fortunately my wife still had her phone and we called some 5-10 minutes after he dropped me off. William circled back and met me at the Delta drop off.
Hats off to him as a great person and many thanks!
