Cemetery Trip to Worcester and Palmer

I just figured out how to make a new post so maybe we can open up a new thread concerning my upcoming trip to Boston 7 November to 10 November to visit two cemeteries, one in Worcester and one in Palmer.  The one in Palmer is considered haunted so if any of you are in the mind to accompany me through this cemetery, feel welcomed ;-)  I need to correct what I believe to be a faulty transcription of a gravestone in the Old Palmer Center Cemetery.  Once I establish that it was 1846 and not 1816 for John Corey's death year I will be able to cite the correction NEHGS will be asked to submit to its vital records of Palmer.  The St. John's Cemetery in Worcester will be easier to navigate since I got a map of the location of the two gravestones I need to document and photograph for submission to Find A Grave website.  There is also, I believe, a Jewish cemetery adjacent to St. John's that Linda may want to add to her itinerary for the Jewish genealogical conference next August.
