We went over to see Bill, drop off the toilet (and cat door) and see what was going on. Because we didn't give him a need-by date, he fell prey to high-pressure from other RV-ers who had "emergencies."
Apparently, he knows this about himself, so he offered to create his own deadline to work against. So, we're looking at about three weeks. I feel better about it not being open-ended.
Local people: I like this guy. He's not slick, not patronizing, and communicates well. Plus, he's been doing this stuff for decades.
