Sorry to come in so late on this, but two hotels, the Gunter and the Blue Bonnet, have been identified as sites of RJ's initial sessions (see article "Robert Johnson: The San Antonio Legacy" in Juke Blues, Spring 1988). The Gunter Hotel is the most frequently mentioned site.

The "three forks juke" no longer exists. It was wiped out by a storm in the 1940s. When it was still a going concern, the place was known as Shaeffer's Store. You can find more information at Steve LaVere's little "blues museum" in Greenwood. (There used to be a second "Three Forks Store," twelve or thirteen miles south of Greenwood, identified on some European websites as the scene of RJ's last gig. That information is erroneous. And anyway, the place was torn down a couple of years ago.)

There are three RJ burial sites. The most likely one is a mile or two north of Greenwood. Again, see LaVere's museum.

More info is available in the text and footnotes of a new book, "Robert Johnson: Lost and Found."
