My late mother-in-law who was born in 1920 in NYC always said it "going to hell in a handcart" which does make more sense to me, so there are regional variations.

@cassandracorvid I've heard both, and that version makes more sense to me as well.

I tracked down the earliest known usage of the expression a few years ago, but I can't find where I saved the reference. There's been debate about whether it was a US or UK usage originally. The usage I found was British.
