Maybe 4 weeks ago was what was to be our second to the last trip of the season.
Usually we plan one last trip with a full hook up so that on the last day I can flush and drain the tanks and winterize when we get home.

Well, because of the colder than normal Fall most campgrounds around us are closed.
My grey water tank is empty.
My black water tank was flushed and then I added a few gallons of water and a black water "tablet".

Can I dump a gallon of the "Pink" stuff in the black water tank and winterize the rest of the TT as usual?

If the black water tank is flushed but contains a few gallons of water and a treatment packet I still really hate dumping it on my driveway.

Thoughts?
