I'm looking for an old friend.

I'm trying to locate Mr. Bob Hubby, author of "Blackjack Tracker."
The telephone numbers I have for him have been disconnected and his e-mail address is no longer valid, nor is his home address.
Does anyone know what's happened to him, or how I can reach him? If so, please e-mail me, or ask him to contact me.
Your help is appreciated.
