People quit and move on in any sport , hobby . For many this is not the be all and end all of life after work , just one part of it . If all the racers in FL showed up for every race you couldn't run the race there would be too many boats and classes would have to be limited . Simply not enough time in the day . There are now too many gas boats and Nitro boats combined to run at the same race it seems . No problem we now have the Nitro Winternationals and we will see how it goes I guess ! I do believe there is a point of diminishing return as far as big races go , sometimes it's just too big .
