We made it! Last night we pulled into my mum-in-law's house in rural Indiana. I was able to give her the hats that I made for her, and the toys for her cats. On the way there we stopped at a Steak 'n Shake for lunch, and in the restroom the counter by the sink was a mess. I pulled out some paper towels and wiped up the water to make it nicer for the next patron.
Today I did some things around the house -- filled the bird bath, watered the flowers, "fixed" a lamp (it wasn't plugged in!), and now we're taking mum-in-law out for lunch and on some errands, and using the free wi-fi while we're at it since she doesn't have internet at her house.
