I'm so sorry for your loss. I can't even begin to imagine how you must feel. She looks like a really cool lady, from the stories and the photos you posted. Playing (competition) pinball, fixing games, baking cookies.
I was thinking of some way to pay tribute and help keep the memory of her alive and came up with this Pinside header background. It will come around every once in a while. I hope you like it.
