Any air brake classes out there besides Bendix?

[belfert]

Are there any air brake training classes out there besides the Bendix training classes?  I would like to avoid traveling to Chicago for the Bendix class if possible.  I know Brian Evans took some sort of class, but he is in Canada and the requirements for operating an air braked vehicle are more strict.

There is nothing wrong with the Bendix class, but the travel costs are more than the cost of the class.  Also, the class in Chicago also happens to be the week after I am doing volunteer construction work at a Scout camp for week so I would need to take two weeks off work in a row.
