the registration for 2018 filled up in 7 minutes. that's 400 cars in 7 minutes. then they took another 400 standbys and that went quickly too. better be ready on the computer when it opens up. my wife and i followed it again this year and it is grueling. i am impressed with the people that participate in this. hard core racers for sure. especially this year. it was very surreal to see race cars with trailers behind them driving in the severe weather conditions heading towards the hurricane while everyone else were heading out of town. would love to participate one day.
