I went to dartmouth for undergrad and after spending 4 years there, i did not want to go back for medical school. However, i loved my time there. So even if you like big cities, for a small portion of your life it can be nice to switch things up. Its also just a 3 hour bus ride from boston and the bus runs 10 times a day if you wanted to get out. there are also 5 hr bus rides to NYC that run once or twice a day. Dartmouth undergrad has a large gay community and since the med school is right on campus you could join one of the LGBTQ greek houses (like Tabard) if that interests you.
