Figured out the route listed above on Google maps and am trying the link out;
Miles St, Greenfield, MA 01301 to City Hall Plaza, Boston, MA 02203 - Google Maps
I put the Bear Hill Rd. Mobile station as destination B as I think this is what Danny was talking about as a possible fill point.
NeilBlanchard, aren't you from Maynard? I noticed the route goes right by there
