Great comments.
And let me point out there is NO requirement or expectation that sponsors must provide storage for mids over summer break. Mids are expected to manage their own stuff, paring down as they need to, using USNA storage, going in with other mids to rent a storage unit over the summer or asking sponsors. We used to allow it, asking simply no perishables, well-labeled storage boxes, and no long-term storage, but we got tired of smelly boxes (one was wet laundry that fermented over the summer), “mystery boxes,” abandoned boxes, boxes of friends, etc. and stopped the basement option. We have a designated closet downstairs where they can stash things for short-term. Sponsors and mids work it all out.
