We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember Steve Walker
saying something like:

You can buy a plastic square for this, it just sits on the washer and the
dryer sits in it - the square just stops the dryer gradually moving and
falling off.

I've had my dryer stacked on top of the w/m for years without any fancy
bracketry at all. Never fallen off.
