Why will it take a month for clubs to remove their stuff from the Activity Center?

If all clubs were available at a certain time on a specific week, it would not take that long.  However, it is summertime and people are scattered.  Clubs may want to inventory their items, decide what they really need to keep, pack and protect items and figure out where they will store them. We want to give them ample time. If it gets done faster, that would be good.
