If the storage room is a climate controlled, ventilated room, I would be likely to keep as much til fall. Or maybe the meds can be given to a friend who might be staying for summer school. I'd hate to see those go a dump somewhere.
Any meds still sealed could be given to a homeless or women's shelter.
Have a dry cleaner clean the coat and recommend a way to store it.
I would like to know more about this mom's group. My oldest is a Junior (for another month) and desires to attend a top tier school: MIT, Cal Tech, Virginia Tech....
That makes me sad. I would like him closer to home. My husband says, "Let the boy go away to school and become a MAN!"
