Colby College has a new indoor athletic facility which should provide lots of non-drinking options.
Wash & Lee’s social life is built around frats & sororities. Might be a difficult environment for a non-drinker.
Drinking is prevalent at small, isolated, cold weather LACs, however, it is not the only social option.
Both are strong schools academically & both offer a strong social scene, but the social scenes tend to have alcohol present.
I cannot answer whether or not you will be socially ostracized for being a non-drinker, but you might be bored & you might be a bit lonely at times.
It just isn’t fun to stand around at a social event stone cold sober when others are getting light headed or drunk. You need to find activities that do not involve alcohol. Easier to do this at larger schools & at non-rural, non-isolated schools.
P.S. Have you read student input on Unigo & Niche & Reddit ? I am an adult poster; it might be more helpful to get current student input regarding alternative activities which do not involve alcohol.
Does either school offer substance free housing ? If so, then you should have an instant group of like-minded friends.
Are you considering any of your other options ?
