Good on ya' for doing this. It is good to be able to use your flying for good effect.

You remind me of a story from a while back. This happened while I was in law school.
Some friends had moved to a town about two hours away, and the home market being very soft, they had been renting their home out. A tenant had really trashed the place, and they were coming to town on the weekends to fix it up, and I was helping. They'd come to town in the van, momma, daddy, two toddlers and Buddy, the small dog of indeterminate breed.
So this one Sunday, after a day of working, they packed up and headed home. That evening, I got a call: in the rush, they'd managed to leave Buddy in the house; could I go over there and get him, keep him overnight? I readily agreed, and did just that, offering in the mix to go ahead and drive him to them, since my schedule was more flexible.
Next day, having collected little Buddy (you shoulda seen the look on his doggy face when I got there!), I lit out to drive to their town, and right away, I discovered that Buddy liked to climb into my lap. And stay.
And...
...Buddy had gas. Really ripe, strong and frequent doggy-toots, real eye-watering, nose-hair-curling, death-stench emissions. I stopped a couple of times so Buddy could download hs solids, to no apparent effect. He was just a small, but potent, pooter.
I was glad I rescued Buddy, but the ride was not much fun!
