I can't recommend these guys enough. I rode out to their Cali location from Houston in fall of '09 and did their school. I'd bought a 09 GSA in the spring of 09 and knew I needed some skill updates as I was riding a 2007 HD Ultra CVO at the time.
I had a helluva time transitioning from the techniques you need riding the big girl to a GSA. I clearly remember the instructors screaming at me "you can use your front brakes on dirt" and "your not on that fat hog now - turn your front wheel in the dirt" as I navigated their training course.
I totally feel comfortable going from pavement to single track (including bowling ball boulders, sand, water, down hill dirt, whoops, etc) after attending their school.
PS. Im sixty but I don't look as old as Jim Hyde. LOL If he gets out of this business he would be successful in anything that demands great customer service and satisfaction.
