He really wants a diverse campus, and that really fits the bill (Macalester). How is it socially there? He will most likely be the one not partying, but he is super social, but doesn’t enjoy very crowded, loud places. So, he won’t be on the “club” scene! His hobbies are government and he plays mulitiple instruments (bass guitar, acoustic guitar, electric guitar, drums, keyboards, mandolin, etc, etc, all self taught. Performs in his school rock band, but has no interest in this being a major or minor. Just his hobby).
Look into St Olaf - not quite quirky but definitely wholesome& super musical (he’d literally find a hundred kids with his passion for learning instruments), and 45mn to the Twin Cities or Mayo.
