U should take a Uber .. there is no easy public transportation to Groton .. you can try for Waze car pool rides if u have couple of days time ..or if you really want to hassle .. u can take multiple trains to Ayer and then take a Uber from Ayer train station .. but with current weather I wouldn't recommend.. 🙂
Uber is the best option. And I agree with Raghu
