My friend Candace's grandfather disappeared

My friend Candace's grandfather disappeared in Cedar Falls last night. If you've seen this man, please contact the authorities. Update: He's now been found! Just got this message from Candace:

Good news! My grandfather has been found near Ft. Dodge. My parents are on their way to pick him up. Thank you for all of your thoughts, prayers and help in spreading the word. My family and I really appreciate everything you have done these past few days. Thanks again. Candace
