Mrs  Elliott's car drools water onto the garage floor after she drives
out and  about the town in the snow and shush. The ice melt drifts about
according  to whim and lay of the land, puddles up here and there, soaks
through the  bottoms of things ... and generally makes a mess.

Is there such a thing  as a rimmed pan I can place on the floor for her
to park on? I envision a  grossly-oversized rimmed baking sheet.

i usually just open a bunch of cardboard boxes and lay them on the floor.
soaks up water/salt. when they get really nasty just throw them in the
recycle  dumpster and get some more.  plenty of free boxes in the cardboard
recycling dumpsters behind businesses..
