Well, it looks like I'm going get the weather I crave. My mom's neighbor, and "caregiver" has decided that he's not going to do it anymore. Since my mom has macular degeneration and can't drive because she can barely see, and also has significant COPD, I will be, at least temporarily, moving out to Arizona to care for her, tend to her needs, and see what kind of in-home assistance she can get, or, in a worse case scenario, look into nursing homes for her. Even if she were to agree to come back east, it will take time to get everything sorted out.
It won't be a pleasure cruise, but depending on how the situation plays out, I may stay out there at least through the winter before I come back to PA.
