I was just going to say this. The hour travel is worth it; call the gerontologist's office and make an appt. and then ask about the best way to get your mom there, which will be the least painful for both of you. Do not let the distance or her complaining deter you. Once you meet with this person, they will be able to help you with all of this stuff. It's his/her job. You may have to pay some $ to get assistance in transport, but again, it will be worth it.

I guess i should appreciate my 87 year old dad, who still lives on his own (with roommates my age). He has medical stuff and a few other oddities, but my brother is there to handle it and overall, he's pretty good. Everyone in my family, except my mom, lived to their early 90's, with full mind and sort of OK body (none of them were active, in the sense that we all are). My mom's father worked up until the day he died at 92, and there were tons of scrap metal sales people vying for his accounts at the end, like "when are you going to retire or die?"
