Where's Ralph?

He is away. This time he gave us no clues as to where he was going until Monday evening. My guesses:

1. Chronicling the real story behind the blue people of the bluegrass state.
2. Trying to figure out what the heck is going on in Gaza.
3. Participating in the US Air Guitar Championships [Ralph"His-Tuney" Luker?].
4. Buying some souvenirs in Chechnya.
5. Paying a visit to Michel de Rochambeau.
6. Telling Dakota Historians exactly what they missed.
7. Trying to tell NBC that they really ought to leave history textbooks alone.
8. Celebrating Juneteenth in TX.

Or not. Do let us know in the comments if you know where Ralph is. Or anything else on your mind.
