To the Siefert family;
I am so deeply sorry for the loss of your mother. I loved your mom, no one could make me laugh like she did. Her and Her pal Sally were a force to be reckoned with. She always had a smile and was THE BEST IN HELPING EXHIBITORS, We spent many a show on the docks working together, she let me pretend I was the boss (I knew better). Loosing Charley hurt her to her core. She LOVED EACH OF YOU AND ALL THE GRANDKIDS WITH ALL HER HEART.
We need a lot more Katies in this world!

Mary Kay , Kevin , Jimmy , PJ and Marny no words are enough to express our deep sadness we share, Big Kay was one in a trillion and we owe her so very much , we would not be where we are today without her guidance and arm twisting (haha) she truly brought joy and laughter into our lives and not to mention a few very colorful words 😂 she spoke the truth and had no agenda. She is now happy with Stumps , Charlie and I’m sure giving her sister patsy a hard time. ❤️❤️❤️🙏🏻🙏🏻🙏🏻
The entire Davey family is better because she was in our lives
