How much would you pay.....

Same here in the UK last year, a normal Pro meet with TF FC etc running would cost approx $300 to enter. Due to the non existent C-flu with travel restrictions for euro competitors there were none. We had to pay the same price $300 to enter for what they called the "back on track day" meet and our other non pro meet type events were the same. There was no car tech and were more or less RWYB type events.
My mate who I crewed for had just spent over $30000 on a complete new set up for his RR and if it wasn't for his wife pushing him to race he wouldn't have paid the exorbitant fees, but what do you do when you've just spent that amount on a car, you pay and race and everyone paid, some entered in 2 classes, wonder how much that cost them. We only have 1 proper track, SPR and at the end of the day if they didn't do that it was quite possible it would've gone down according to the CEO. If we ever get to race in 2021 it will be the same no doubt.
