While I love UMass very much for its quality of education, the campus, safety and the best food (#1 and I have tried it), don’t discount the freezing cold, long winter. Your child is from SEA. New England weather can be miserable for her. Also, flying extra 6 hours from west coast to east coast plus driving to UMass can be tiring.
Weather alone is why many SEA people prefer CA over any other colder regions of the US.
