Thank you all for your kind words, support, and your prayers. you have noidea how much I've appreciated them.
Dad is doing much better. Monday night, when they wheeled him off to the hospital I seriously doubted he would make it until the next morning. I underestimated the crusty old dude. He's been up out of the hospital bed sitting in the chair these past few evenings. He needs a little help walking but his walking is MUCH better than we'd feared.
Mom and I think that if we can get her some full-time help, there should be no reason Dad can't come back home soon, which will be so much better for him than a care home.
