Have a safe trip, Sandy. You're one special person for inviting your Mom to come live with you. Lots of people wouldn't take on that kind of responsibility. I admire you and Jim for opening your home. I know it's for family but even so.....many people wouldn't do it.
Take care of yourself, too. It's easy to overdo it and then pay for it later (I know about these things!
). You've got lots of prayers and good thoughts behind you. Have a good trip!
