They want to keep there numbers secret
Doubtful but there pears may rub them
Exactly
Most people that race the back all say ways or way off the beaten path side roads and industrial parks keep their ride info to themselves so they can gauge who and who not to race or bet against. These races are mist just heads up but a lot of times they ask for the leave or a cars length head start.
The way I did it was heads up, not giving you anything, arm drop and go, no crying or excuses, be ready at the line or don’t bother me. Video finish with the third party deciding winner. The third party consisted of the arm drop man, finish line man, money man.
Just getting together and hanging out I’d guess.
