Nah. If the WRTA makes any changes, they should be cutting routes so that they're more condensed and focused on serving high frequency corridors in the city limits over sprawling geographies where ridership is lower. Get the city right first and immediate suburbs right first - high frequency service, rapid lanes, high traffic corridors.

The furthest out stops should be right now are places like Shrewsbury, Auburn, Cherry Valley, West Boylston, Holden, etc. Direct routes right into the city for commuters to have an option where they can avoid hopping on 290/190.

Once we actually get ridership and reliability established, then explore those connectors.
