hi all, i'm new to SDN! i volunteered at tufts for a bit, and you'll definitely need a car. it's about 45 minutes from boston, give or take depending on traffic and where you're flying into. the campus is beautiful, and has a lot of great history. the closest big "city" to tufts is worcester, but you could also stay in framingham/natick if you're okay with driving 20-30 min. no public transit that i'm aware of in north grafton. also check out airbnb or bed and breakfasts- north grafton is just a pretty small town!
