As for checking in, I would suggest contacting whoever you report to or whoever might be in charge? Lots of times at events the whole facility is rented by a race company such as Honda Motorcycles for testing and they don't want "spies". It is a great place to race and here is a shot of us at the first one they held a long time ago. At first they put in a "chicane" before NASCAR turn one as they were afraid speeds would be too high for folks! Testing proved to not be the case and it was removed.
