Thanks to all for their prayers and positives thoughts. My dad had a rough night last night so the doctors have decided to keep him in the hospital (he is in the tiny hospital their tiny town has) until they scope him on Tuesday. Today's x-ray showed that the blockage seems to be moving/breaking up so that is a great sign. My dad is complaining about the clear, liquid diet they have him on - yet another good sign. My older brother drove down to be with our parents and will return tomorrow. Looks like it is time to coordinate with my other siblings so that someone is with them until the results come back from his scope on Tuesday. Please continue to keep my parents in your thoughts and prayers. I appreciate all the good vibes.
