More anonymous advocacy re the MGHRS renovation vote -- this time from the proponents

Update: Wendy Penner reports:
The mailers were sent out by the Build Mt Greylock ballot question committee which has filed with both towns. Led by Cheryl Sacks and Valierie Hall, Treasurer Jim Majhon. The group has been holding and promoting outreach events and asking for donations from supporters. You can see the FB page here: https://www.facebook.com/groups/1172847762733072    Hope this helps! 

Large postcards were delivered by U.S. mail to residents and businesses in Williamstown (and probably Lanesborough, too) promoting the renovation of Mount Greylock Regional High School. The postcards say only: "Preparation and postage paid by the Build Greylock organization."  Who's that? Speak up, please.
