Well someone has to post something to this Somerville Community… So it has to be something about the community path obviously…

Google maps is always rubbish for bicycle navigation, but OpenStreetMap offers three different navigation systems for bikes, all of which are better. I’m most impressed with GraphHopper - 3 days into the community path opening will happily route you down the new path. It doesn’t seem to know about the High School diversion, but that’s realtively minor.

Its route for me to get to the Seaport from near Davis is pretty much what I would choose.
