Kelly,
I wouldn't worry too much about it just yet. The OBX 500, Tybee500, and the Atlantic 1000 are very young. I'm excited that the OBX and Tybee provide an event that us working stiffs can do with regular vacation time. I think we will see both of these events continue to grow in the future. The race organization was great - especially considering that this was only the second running of the Tybee500. It will just take a little time for them to grow and reach the same acclaim as the Worrell had.
