Juggling Schedules

All of a sudden it seems that all of us have gotten extremely busy.  Maybe because it is spring time and more people are getting out and about or maybe it is the rush to fit everything in before people start vacations.  I am trying to figure out the best way to organize 5 peoples schedules and keep my husband in the loop.  I have not found the perfect system yet, but I can see why families go to color coding!
