If its in mass, the property probably belongs to mass development? I think thats the name, I may have a lightbulb moment later.
I would probably say they wouldn't just give it to you. I work for the state, all the excess state property (this ISN'T including forest service FEPP) gets trucked to Westborough to the old state hospital. There is a facility there which holds auctions, which are advertised in the Boston globe. Sometimes stuff sits there for a few months before it gets auctioned; I know, I've brought vehicles there a few times!
Plus side is, mostly scrappers bidding...on a vehicle with a poor description.
The reason it's there is the state department in charge dosent have the means to move it themselves, and it isn't high up on their list of priorities. I would GUESS, that it ISN'T FEPP (forest service) property or through GSA, a lot of vehicles AGES and AGES ago were obtained through C.D. funds. There are many, many different ways to get these from the government, one of which is the now defunct north star. Several local DPWs have northstar vehicles...despite it being a "law enforcement" program.
Good luck, to be honest good luck trying to get anybody at the office/management level to CARE!
But keep us updated man!
