I have a suggestion. If you dont want to have huge lines or angry people. Andrew Dougherty made this suggestion at our Roar nats.
Hand out tickets and call numbers for people to come to motor tech. Call people 3 at a time and then you wont have huge lines of people wasting their time. When there is 1 person left from the 3 call another 3.
By the look of the entry list there will be upwards of 700 motors to tech. At a minute a piece that is over 10 hours. You probably see where I'm going with this.
Again just a suggestion but something to think about.
