Hello Mandy,
We hired a car with Satnav for Boston back in 2011. I drove, my daughter map read. After coming out of the tunnel, I was presented with a 5 lane highway on the left side when she said I needed the next right. Brown pants time :blush: There is a great Metro system which I believe went to Logan Airport.

Oldest subway in North America as well and fifth oldest in the world, only the Metropolitan Line, another in South London , Budapest and Glasgow are older. That might come in useful at your next pub quiz! 😛
