Expired film and kids

I've unsuccessfully tried a few expired films...they've all turned out fairly yucky, looking muddy and grainy. I recently gave it another shot with an expired pack of Portra 160NC and I really love the way it turned out. Here are a few examples. Oh and that blonde lady is my mother. She is just awesome.  

I've also continued to have a lot of fun with the Rolleiflex. It's a really handy camera for snapshots of the kids.
