I hate to say it MJS, but here in CA, you might see $100/hr lessons from people who aren't even in the same caliber as Rickson Gracie. It's really a matter of who you know, and how well you know out here. I've seen wannabe-instructors offering lessons for outrageous prices, as well as solid, stand-up instructors only asking for enough to help pay the rent.
Umm I think its pretty much widely accepted that nobody around today is on the same calliber as Rickson... and before him Rolls... but hey you are correct. I know of brown belt instructors in California that are getting over $100/hr for private lessons.
Agreed on both posts. I threw Rickson out as an example, but any name can be inserted there.
