Hi Bob,
I did my first track day last summer with Nesba and ending up doing 3 more last summer. I finished my first track day this year yesterday at Road America in Wisconsin. I'm a much better rider now and have made a few new friends. When you do your first track day, you will be a little nervous....but you will definitely enjoy yourself. Make sure you take the time to say hello to others that are at the event. I have learned a lot by asking questions.
