Brad, I'm not a praying man, so I cannot offer that, but I wish your dad and the family & friends who love him the best through this hard time.
I have the same love, respect and regard for my father as you do for yours. It brings a tear to my eye to even think about dealing with a situation like that with my father so I cannot truly fathom what it's like to be in your shoes. Stay strong, take the hits as they come and appreciate the victories as they will inevitably come too. No negative is too large to overcome and no positive is too small to celebrate.
Take care.
