I like RMA days as well. You can plan where to pass, and it's like driving on the road - keep an eye on what others are doing and anticipate. Much less frustrating than sitting in a line on an 'overtaking on the left' day with someone who doesn't want to move over or doesn't look!
I didn't use to like track days, as they seemed like weak versions of test days, and traffic etc would annoy me too much, but once you get your head round them being for 90% driving in cars that you can't exploit elsewhere, it's all a lot more relaxing/enjoyable.
I just ignore Graham's rants. Last time he called a start line get together for a blocking, I sat in the cafe (with Nick and others...) and finished our coffee!
