Winterizing Question
In the winterizing process, after emptying the black tank and using compressed air to blow water out the black tank flushing line, am I correct in assuming that I do not restore any black tank sewage ...

It's the water under pressure (or at least fills up the pipe) that is left in the small supply pipes that will expand when frozen and split said pipe.
It's water in any confined space. I've seen a little bit of water trapped in the threads of a water filter canister split the threads of the cannister. I've had lawn sprinklers split open even though they where not capped and there was room for water to expand. I've had a small drop of water in an air compressor filter drain split the drain valve open. I'm not about to risk having a sewer valve split open because there was a little water between the blade and valve body - not when it's so easy to prevent with just a little antifreeze.
Good points, sounds logical, I'll reconsider, but it's never happened to me in over 25 years. I think I see the difference in our points of view, here in the Pacific NW it doesn't freeze much, if it does, just a little below 32 (unless we get a northeaster, but it lasts less than a week). I assume it gets really cold for extended periods of time in Buffalo?, therefore antifreeze would be mandated.
