Does anyone still wash with washboards?

My question is inspired by this thread about whether anyone still uses steamer trunks for their original intended purpose.

I bought a washboard recently to use as a percussion instrument for old-time music, but was wondering if anyone still washes with them.

They still sell them at all rural hardware stores.
They are used a lot for tents, large sheeting, and tarps and such that can get caked with dirt after gullywashers, but are not worth hauling into a laundromat, even if they would fit.
