Motorcycle Training. Help or Hazard?

[4 Paws_imp]

Here in NC there are "advanced" rider classes offered for free or almost free and taught by motorcycle police officers where they team you with a coach who observes you riding on the street. Two riding sessions and some classroom work.
Make me a better rider? Yes. Permanent improvement? I'm more aware of what my coach recommended I work on.
Got to meet and ride with some LEO's who ride professionally and spent a day riding on some country roads. Held at local firehouse so the firemen provided us lunch.
Good fun, no hurt feelings. Strong cost/benefit ratio. Any advantage gained is a positive.
