Last Saturday I found Gary and sang (to the tune of Celebrate by Kool and the Gang):
"Cel-e-brate drive-way, comeon!"
At long last (specifically one month) Gary has deemed the driveway accessible to all. He says he is now comfortable if a truck gets on it, even a plumbing truck. He claims he will call a plumbing company soon so someone can install the upside-down toilet.
