It used to be that my wife could detect the sound of a new engine whistle and say, "What is that? When did you buy it?" - (in other words - you spent more money?) but, no more. Sheer numbers have finally dulled her level of sound discrimination to a safe level.... I can run a new engine and blast away with impunity, well, er - as long as I don't over do it.
On our last trip to the Outer Banks (it is either that or Myrtle Beach which is considered the French Riviera of Pennsylvania) she even bought me, of her own volition, a somewhat overpriced Weaver track cleaning car.
So maybe there is hope for changing times and detente evolving into a complete armistice.
The attached photo of her was taken just after she actually checked out O gauge prices for herself to see what all the new freight cars were costing me.
She is much gentler than she looks, usually.......
