@Hoghgyni One parameter that we all agreed on (including DD) was that we would only look at uni's that were within a four hour drive, or about 250 miles. We're in New York, not all that far north of NYC, so we are spoilt for choice as you Brits would say. Many of the best US universities are on the US northeast coast simply because that part of the country was settled first.
Bryn Mawr is in a suburb of Philadelphia, so about 3-4 hours south of us. Smith and Wellesley are in the Boston area, so 4-4.5 hours north. Clark is the closest in central Mass. so about 3 hours away. DS is currently in his second year of uni in Boston, so logistically it would be lovely if she wound up near that. We have loads of family in the Boston area, so that's another plus for those options.
We just bought a bigger car, a Subaru Forester, to help manage the fall drop off and spring pick ups more easily. For all other trips back and forth they can take the train.
And I forgot to mention, best wishes and good luck to your DC as they make their choices. Is anyone on the thread looking a university options in America?
