A hint to the code

Yesterday's hint to the code:  The numbers will NEVER change again.  EVER.

Today's hint:  John and I do not know our code (we could probably ask around and see if there is a ballpark or exact number).  I do know a ballpark number of my Dad's code if he had one this year with us.  It would be in the upper 20's to lower 30's (once again, I'd have to ask around).

Jaley has been hard at work trying to crack it.  I love some of her possibilities ... but then when she thinks about it, they don't make sense.  How many pillows are on their bed (53 would not be an unrealistic number ;o)  ).  How many shoes they have.
