Internet Gates BBQ sauce recipe - authentic?

[cdcox]

I don't live in the KC area or I'd just go out and buy some. And yes, I know you can order it through the mail. But I found this recipe for "Gates BBQ sauce" on the internet in several places. Has anyone tried it and found it to be somewhat similar to the original?
