This is the website of Roger H. Johnson, known by many as "Roger the Real". (the other Roger is merely famous).

If you came to find the Solo Course Design Manual, WELCOME.
You have found the Correct Roger, but not the correct location.

The Course Design Booklet can be downloaded from the Houston Region SCCA website (www.houscca.com) via the folllowing URL: http://www.houscca.com/solo/courses/coursedesign.zip (a 4+ Mgb file, so be warned.)

Hmmm....
I guess you DID come to the right place after all!
It appears you may have found the course design booklet - didn't you???

Don't forget to check out the links in the upper left, above my steaming head...
