Found.

I looked everywhere for the vinegar yesterday, darn sure I remembered buying a big jug of it.  Could not find it anywhere, not still in the car and not, as I thought might be a possibility, sitting in the flower garden, next to the car.

I do vinegar treatments to the shower curtain and the coffee maker at the beginning of each month and I had only a token amount left in the jug for the February treatment so I really wanted to get it done.  Now.  Very aggravating to be so thwarted when I was so prepared for action.

When I flung open the front door today to let in some springlike fresh air, there it was.  I seldom use the front door but I must have brought things in that way when the ice slick was by the back gate.

Let the treatments begin!
