I am not incredibly active with groups/organizations at BU.
However, in my free time, I enjoy climbing, being outside in any(or most) capacities, and traveling.
When I lived in Oregon, I was active with the organization Friends of Trees.
I guess I am technically a member of the BU Undergraduate Economics Association.
(As it turns out, they don't have a website. So that link goes to all of the Economics Student Organizations.)
