Petrie phone number

In case anyone keeps a list of trivia that
might have been missing this little tidbit,
in the episode I am watching right now,
Laura mentions the Petrie phone number when
speaking to the Coast Guard about Rob and
Jerry, who are missing. The phone number
is 636-9970. Combine that with whatever the
area code for New Rochelle was/is, and maybe
someone might want to call that number and
tell them how lucky they are.
