Sidecar training

I’m a new member looking  for a sidecar and investigating sidecar training. I did a forum search but the lates response to training is over 2 years old.

so what’s the deal? Do I have to take the plunge and buy a sidecar rig, then shop for training somewhere?  As far As I know it’s not a requirement in California but I’d sure like to take a class somewhere and I assume I’d have to have my own rig for a class, so the logistics are a bit problematic.

any Input?
