missing pictures

I'm realizing that as I'm going through all these pictures from ages ago, I think that I am missing some.  You wouldn't think I would have a clue as to what pictures I remember taking, but I am pretty sure there are some missing.  As much as I can't STAND to go out of order, I'm going to keep plowing ahead and know that I WILL have to go back and find those darn pictures!  (I'm afraid they are on one of our old phones...)
