    There are stories to be told. They are stories of the pains, pleasures and the mysteries of life. We each and all have our story. Some are epic novels to be enjoyed by the masses; some are but simple tales that remain on a dusty shelf, only to be known by a privileged few. From one page to the next our story is told until the final chapter, when the Great Author who knows best when to rest His pen, brings our story to an end. -Richard A. Snipes,

    Al, you were a renegade! You were modern day Superman. You made a world out of nothing. You were spectacular and funny. No one else was like you or will ever be. You were so carefree yet professional, so down-to-earth, so brutally honest, so open, and so very caring. Family was above all the most important to you, and you always made it that way for your employees, too. You were a perfect puzzle. Thank you for allowing me to work for you and get to know you for a few years. Rest In Peace! You’re damn amazing and will be missed but never forgotten!!
