My letter for Michael T. Weiss' birthday 2020 to his then management was returned with a postal sticker attached, reading "Return to sender, Attempted - not known, Unable to forward."

Prior to his 60th birthday on 2/2/2022, we contacted every possible agency, only to hear "The number you've dialed is no longer active", wrote to many addresses if they would handle fanmail for him, but never got answers, only found that most of their websites were no longer active.

With thanks to Gail Moss, a long time fan of MTW, who posted this info on our Facebook page:
"I called on November 8, 2022, and spoke with an employee. This is his current information."

At least, my birthday letter 2023 still wasn't returned eight months later.
Mike's definitely gone off the grid. I hope he is living a life that makes him happy. That's the best we can hope for.
