I'm interested in doing a more advanced racing school between seasons. From searching there's only a few, Skip Barber, Allen Berg... Are there any I should be looking for that I haven't found? I have my SCCA license and have raced endurance for years before that, but would like a more focused school, or something for experienced drivers. I feel like a beginner racing school like they offer may not be the best use of money due to my experience, but also not sure about that. Any advice?
