Does Winterization have a mayfirst list? If not, do they want one? I can
get that started. I just need to know who wants to be the owner. how does
one get in touch with Winterization? Is there a list going within
Winterizatiton regarding residents nearby willing to open their doors to
Occupiers for a break/shower or rest from Dewey Square? Thanks!!
