Tufts has a “LAC like” campus located in a city (Somerville) with the second highest density of young people in the country. Adjacent to that is Cambridge which has the third highest density and where you will find MIT and Harvard. Adjacent to that is Boston where you will find Northeastern which has some green space. BC is in the wealthist city (Newton) and feels more suburban, but has good access to Boston. Brandeis, in Waltham also might work. Clark University, Holy Cross and WPI are located in Worcester which is slightly larger than Providence.
