Badly Shook Up

This postcard shows a scene in Yosemite, but it was sent from Oakland, California.
The message reads:

Dear friend.

We are saved but badly shook up are on the move.

Regards from your friend Kluske

This card was a bit of a mystery to me until I took a closer look at the date. April 22, 1906 was just four days after the San Francisco earthquake.
