We made it home! It's been a really long day, with a ten-hour flight plus a broken air conditioner to greet us when we arrived. The house was 96 degrees inside. A quick call to our trusty heating and a/c company got us a $300 repair, and we should be back to normal by morning. Meanwhile, we've decided to have a backyard campout tonight, since it will be in the 70s overnight. I made a quick trip to the grocery store and discovered that I do remember how to drive, despite nine weeks as a pedestrian. So all is well, other than the jet lag, but a good night's sleep should fix most of that.
Edited to add: The air conditioning managed to get the indoor temperature low enough for sleeping before we went to bed, so we did get to sleep in our comfortable beds after all. What a treat after a long day on the plane!
