My dad is in the hospital again.

I had encouraged my siblings to get permission from our dad for them to examine his mail. They have and have luckily discovered that his cronies have not significantly manipulated him, financially. We were worried about that. He has been giving loans to one man and another woman has convinced him to pay for two round trip flights to California from the east coast. He also bought her an iPad and several little things. There are other things, as well, but not very significant (buying art, etc.)
