I was glad to see, googling for illustrations, that the hardcover edition shows the proper vehicle, sneaking away from Detroit heading for Route 66. I'm trying to find the right way to persuade you to get hold of this novel, because I know you'll enjoy it. Granted, there aren't too many stories with protagonists in their 80s, but it is totally captivating. Of all the review raves (it must have been one of those that put me on to it in the first place) the one I like best calls it "Kerouac-lite...On The Road with shorter sentences and less drugs and sex."
But not, I would add,
P. S. I know I promised to stop already with the winter complaints, but this morning I finally succeeded in photographing a snowfall -- don't know if the flakes will show up on your screen, but anyhow, here's what today started out like. For a change.
